Ritsueto Remina, the Abyssal Omen, is the regal prince of the Abyssal Empire and the anti-villainous deuteragonist of the BioMassCore’s storyline, serving as the rival to Elpis. He is known infamously by his Homunculi title as the 0th Velcryth, Haos Powehi and has had a reputation for a destructive incident in his ritualistic birth. He was formerly a part of a special ghostly clan unit of Black Velcryth used in the Lux Order of Providence, whom secretly used them for research and saw them as outdated compared to their other unit that overthrown them when the Lux Order betrayed the Abyssal Empire after numerous records of conflict between the two factions. In his wander across history, Ritsueto wishes to find purpose in life within his kingdom’s expansion and cure impure existence.
– Personality –
Ritsueto is a flamboyant and manic individual who believes that all existence follows a predetermined course. Being Elpis’ exact opposite due to how he’s highly expressive, but lacks his own sense of self. With his performative side, he lives for the crowd and cultivates a palatable image. Over-articulating himself with gestures that linger too long, smiles that curve too sharply, laughter that descends into madness. Even treating the most mundane with ceremonial acts like turning elegantly, bowing, or elevating his voice like an orchestra. Ritsueto feels emotions intensely and treats life as a performance with him filling in a role. He sees this role as one who forces people into unity through fear. To be united is something he treats as part of “nature’s course” or “the greater good” due to how everyone inevitably returns to the same place once they die. He doesn’t see any hope in fighting against nature due to how he doesn’t trust that basic morality will save people. Rather, he’d prefer to serve like he has nothing to lose so he won’t meaninglessly waste life dedicating himself to individualistic needs only to lose again. He’s both dutiful and chaotic, refining chaos to fit his idea of being aligned with the “greater good”.
However, in his life, he has an inner contradiction that he denies he’s working towards. His relationships with those like his sister Isobel, or those who see more in him such as Cygnus unravel his martyr complex. Through his self-hatred due to how he was born unnaturally like the Vessels, he sees himself as part of what took away people’s way of living freely. Thus, he has a strong compulsion to compensate for his feelings of deficiency by contributing meaningfully towards society. He sees his own existence as something that interferes with his beliefs, thus loathes himself. In his eyes, he and others suffered because people lived separately through their own selfish needs rather than indulging in values that harmonize each other emotionally or physically. When his role and / or purpose is questioned, he slips into hostility due to how it’s the only thing that’s brought him a sense of comfort in life. Causing him to oscillate between grand proclamations and brittle defensiveness.
Out of shame for being what he is, he desires to give away his individuality and turn himself into nothing to give others something to live for. But to escape this harsh truth of himself, he sinks deeper into his performative side as part of escapism. Once using it as a way to force humanity to fear him, so Isobel could be able to live amongst humans freely without fear of being oppressed like she was in the Empire. So he enforces his idea of living life, which is to either become like him or just surrender to inevitable detriments of life. But when his illogical ideas are challenged, he shifts into resentment because such challenges force him into moments of stillness where his role loses coherence. In response, he chooses to reframe those who oppose his views as someone who’s naive, selfish, or irresponsible, someone who can afford idealism because they haven’t suffered as deeply as he has.
– Relationships –
- Equinox: Equinox often claims he has Ritsueto’s best interests at heart, steering him into his way so that his individuality doesn’t go loose with his instincts as he feels Ritsueto is the most perfect of his Velcryth and doesn’t want that to be tainted. But Ritsueto feels distant from Equinox in a sense of confusion with their general bond. Something that Equinox constantly attempts to re-assure him with before Aheri’s death, which had caused Ritsueto to make his attachment focused on Equinox. Ritsueto doesn’t want the image that made him to be lost like the woman that brought him his emotions. Equinox however refuses to accept Ritsueto sobbing for him, and never wants to see him saddened when his existence eventually must fade. Ritsueto generally attempts to keep himself tame in fear of shaming his lineage and keeping Equinox impressed. He fears that if he were to shame Equinox that his potential lineage would be tainted with the simplest mistake, thus not even by command but by instinct he’d slit his arms with his own fingers if he felt he has done something his father didn’t appreciate.
- Aheri: Ritsueto believed Aheri was someone of free mind and pure individuality. He had found things to care about before and after her death. Aheri was essentially the one that indirectly gave him his own sense of sentience by teaching him the meanings behind emotions that he didn’t understand well. As part of a sign of appreciation, Ritsueto feels attached to her in a way that he wanted to impress her to feel like he’s ascending to different signs of emotions with his free will. Ritsueto keeps his amulet as part of remembering Aheri.
– Abilities –
Ritsueto is a special organism that evolves over time by consuming others. His body centers around a metabolic core—a dense organ implanted with remnants of a defective nuclear core that has been exhausted. This nuclear core now functions like a blackhole, drawing in surrounding matter and energy into its hyper-dense interior, where it is instantly converted into chemical and electromagnetic energy that fuels Ritsueto’s muscles, magnetic fields, and specialized conductive organs. Because of this nuclear core, Ritsueto’s digestive system cannot process complex plant or animal tissue and has become specialized to extract nutrients directly from blood cells. Ritsueto extracts oxygen from blood cells through gills on his neck, allowing air and the blood cells to flow over highly vascularized membranes. These blood cells are compressed in his gill system then collapse to become dark particles that release a radiation wave upon critical mass, creating an antimatter-like effect on surrounding targets that nullifies their abilities when attacking / countering. When consuming others, Ritsueto’s jaw unhinges to reveal rotating muscular rings that grind his prey, along with a circular digestive moat that dissolves tissues before full ingestion. When Ritsueto consumes someone, he records their genetic and neurological information. Gaining their memories and combat abilities that he can then replicate.
The core converts food into usable energy instantly, with Ritsueto’s power fueled by compressing matter into his body through consuming others alive. The resulting energy flows through his conductive organs, which store specialized cells as energy reservoirs. Ritsueto’s organs store his particle-like cells, releasing when activated to compress and solidify into a living weapon. His muscles are organic and flexible, capable of stretching, growing, and strengthening through rapid metabolism and adaptive remodeling. These tissues also store extra high-energy compounds for bursts of power, similar to how cheetahs or hummingbirds store energy for sprinting. When triggered, Ritsueto’s cells release energy quickly to activate his abilities. His dense tissues act like conductive and magnetic structures, allowing him to pull minerals and armor toward him, launch projectiles with sudden energy releases, or amplify his own muscle contractions. The broken nuclear core now operates with a magnetic well that holds together fragmented bodyparts through magnetic actuators linked together through a magnetic field. Because of this, he can detach parts at will, hover limbs in motion, or coordinate them simultaneously. He can control each body segment individually, linking them together through biomechanical tissue in the form of dense, thread-like biological fibers that function as structural support and neural extensions.
- By vaporizing the moisture in his body, Ritseuto can absorb heat from living beings he comes into physical contact with, freezing them and stifling their blood flow
Ritsueto can convert thought into energy once he has absorbed sufficient nourishment, allowing him to manipulate all physical matter by generating magnetic fields that attract metals and neutralize external forces. When pulling matter toward him, he compresses it to extreme densities until their molecular structure fails, causing matter to collapse and create antimatter from energy fluctuations that infuses his dark particles of antimatter with particles of high-energy matter he consumes. Ritsueto’s organs temporarily separate matter-antimatter particle pairs, allowing him to absorb and redirect it outward, creating a pulse of radiation that nullifies targets and distorts matter. Such as erasing walls, dissolving armor, deleting projectiles mid-air, or erasing parts of enemies. While compressing, Ritsueto absorbs before having to release it for an explosion, similar to collapsing a star then releasing it.
He is able to extract the maximum energy from a target by pushing them to their physical limits—prolonged, high-adrenaline fights yield the greatest energy output. Through direct contact, he can disintegrate matter in a manner similar to antimatter by detonating magnetic fields, producing devastating explosions. When touching, the molecular bonds of the target destabilizes and their external structure collapses violently. Alternatively, he can repel objects using strong electromagnetic fields. This ability to compress and repel energy also serves as his greatest defensive asset, enabling him to absorb incoming attacks and store their energy for counterattacks. The amount of energy stored in these counterattacks causes his explosions to scale in size, potentially producing bomb-like blasts at their maximum intensity upon colliding with surrounding matter.
By controlling electromagnetic fields, Ritsueto can fly at variable speeds by reversing magnetic polarity, manipulate a wide variety of objects, launch numerous projectiles, and amplify his muscles for more powerful strikes. With his projectiles, Ritsueto pulls in enemies over time with bolt-like spears. Using reversed polarity, he can also control the magnitude and direction of forces around him, redirecting energy through vector-like manipulation. Once a vector is identified, Ritsueto’s bio-electromagnetic field can alter the path of matter or energy in a gust-like motion. Granting him great mobility by repelling himself while flying. Ritsueto’s vectors affects the direction and speed of his gravital traversal whether on sky or air, changing direction rapidly to dart swiftly, creating powerful currents to propel himself, allowing for swift maneuvers and aerial acrobatics. He’s able to alter his speed, magnitude force, velocity, and trajectory on himself and others to outmaneuver opponents, changing his direction and launching things with enhanced velocity in motion. Creating complex movements to enhance his reflexes and fluidity with curves or non-linear paths in waves, generating powerful energy blasts.
One of Ritsueto’s signature abilities is turning his zanbato sword into a drill, charging it with stored particles as the blade spins rapidly to generate intense aerial pressure that compresses matter around it. When thrown, it releases a massive vortex that collapses matter inward as it spins, pulverizing everything it strikes. It can only be countered by an attack of equal force. His sword uses anti-gravital devices to push himself forward, causing distortions on each hit. Upon rapidly spinning his sword as a spear, he creates a blackhole through centrifugal pressure and air spiraling inward, compressing matter into a tight vortex
- Ritsueto is able to pressurize bodily liquid in his eyes and create small openings that unleash two fluid beams with enough power to cut through stone
- His eyes grant him kinetic vision into reality, having extraordinary perception and is able to sense the flow of energy.
Sometimes extending to bending reality to his will through distorting vectors to temporarily warp space for a tactical advantage such as generating enery fields, teleporting, altering gravity, negating elemenets or affecting quantum strings through distorting life and the environment. With the symbiotic Heliusseura inside Ritsueto’s rune, he is able to perform many things primarily with his Metagallion, Drazenith Zetsubou. Such as creating matter out of nothing through treating his protoplasms like quantum foam which affects the tangible and intangible with phases of expansion, often recycling the matter from the dead and absorbing their aelophis as distortional mass through a gravitational field. Allowing his body to expand more as he influences the cyclical processes of energy and matter. shifting the magnitude in his attacks through charging himself with a pressurized warp that shifts the power and size of his output. It can also influence his body in centrifugal and centripetal motion through creating sharp extensions of finned wings for angular movements.
The more energy added to Ritsueto internally, he becomes like a burst of energy with the output of his attacks being through pressurized mass of his protoplasms in parallel to the stored chemical energy of Ultfinite’s organic material. Whenever Ritsueto warps, the air is briefly twisted through the pressure he puts onto gravity. but only if an equal volume of protoplasms is allowed to go up against the force of gravity. performing unconventional maneuvers, such as making sharp turns without losing momentum, creating whirlpools of energy, or defying gravity to a certain extent. Ritsueto’s trails leave behind glowing energy ripples, shimmering distortions in the air or water. He adapts to different terrains seamlessly, allowing to transition between any environment. By reversing the direction of his movement vectors, he quickly warps back to a previous position. He can form distortional fields that shift the weight of objects with inertia and magnitude, entangles them through particles or reshapes them. If he wishes to make objects as light as a feather, he decreases their inertia. This also applies to himself, making him move quicker through acrobatics unless recovering from a charged attack. To keep his body in synchronization during interdimensional travel, Ritsueto uses phantasmic bolts to bind to keep himself and utilizes quick dashes through self-propulsion. Through manipulating the inertia of himself when properly stanced, Ritsueto’s Drazenith forms an accretion disk shield when parrying attacks or deflecting projectiles.

Drazenith Zetsubou: A double-sided combination of a jagged zanbato and a trident that causes decay with it’s attacks due to how it has a saber-like frequency, destroying the bonds between atoms and molecules due to how it negates aelophis. Ritsueto is a disruptive force that flexes his blade in elegance and connective nature with how he uses his flurrying attacks, extended techniques, outward curves, executional strikes, vertical chops, wave cuts, multi-directional bends and fluid rushes. Performing great feats such as larger blade transformation, molecular binding, mind splintering, matter distortion-melding (Phasing his blade through a melding distortion), spatial fabric-cutting, etc. Ritsueto can charge his binding distortion within his blade’s handle to draw in gravity for a triggered Iaido slash emitting the sword’s winding stream-pressure as a blasting ripple wave to counter any mutant potentially. Overdriving by disrupting the electric signal in their lifestream and can use his arm to crush someone with gravital pressure to forcefully transfigure and decay via a detonation, reversing any fusions. His electric signal disruptions come from his development to be the ultimate cure, projected into his body’s stream of energy as some type of anti-electromagnetic sap.
- Ritsueto’s gills require constant aspiration through his Vaesir Drive to breathe and perceive properly, thus compensates by making his fighting style based around breathing out his attacks in direct force. Mimicking the nature of elements through curving his movement.
Drazenith Zetsubou is linked to a grappling set of rune-geared equipment that enables vertical maneuverability, set around Ritsueto’s waist as a bodily harness linked to a machine on his back known as a Vaesir Drive. The Vaesir Drive has batteries charged by protoplasm-atomic energy oversurging due to it attempting to mimic the Aether that came from it, and is administered with Ritsueto’s Arcane Drive labeled Laplace, the last Fermial of a lost continent. Laplace speaks in static and sends information of the precise location and momentum of every atom in the universe with past and future values, preparing Ritsueto for coordination in vertical movement. The Vaesir Drive is linked to Ritsueto’s brainwaves, allowing conversion for him and Isobel.
To maneuver more quickly, Ritsueto projects a phantasmic bolt from his side-equipment in the form of a talisman chain of magic amplification that he can use to either assault enemies or quickly warp himself toward it’s target. Blending into his surroundings by creating a warp illusion similar to the event horizon of a black hole, making him almost invisible or highly resistant to detection for a second. This works in unison with the materials in Drazenith Zetsubou allowing to cut through the weaknesses of mutants such as Ultfinites or Nosoimones. The phantasmic bolts are produced through Ritsueto consuming matter of fallen beings to produce an attracting light in the electromagnetic spectrum in the form of dark energy. Similarly to Gestalt Calibur, Drazenith Zetsubou can parry shots when entering a defensive block stance that turns Ritsueto around with the coated blade of Drazenith to reduce damage and countering toward a brief prompt. but doesn’t have any cancels when dodging or parrying.

In other cases, Ritsueto can either use his turn Drazenith into a bellow trident/glaive through using it’s collapsible mechanisms.

Rolling Thunder: A pair of jet-powered clawing gauntlets and grieves that can summon multiple hands. Drazenith can shift into winged fin extensions for Ritsueto with scythe/sai-like blaster tonfas which hilts Rolling Thunder with his maneuvering gear, the Hayate Busters (Labeled IZ-PUNISHER). The Hayate Busters use high-pressure jet magazines in the form of hilts that provide powering cells to them to fire blade-shaped projectiles via Laplace that have low damage. When firing projectiles, Ritsueto slashes with his Hayate Buster to unload the magazine in thrusts and can chain damage with Drazenith. Usage of this weapon stance allows Ritsueto to perform attacks that can bypass blocking enemies but can be interrupted easier during combos. It can bend the trajectory of Ritsueto’s movement, attacks and projectiles. Said to be ripped from a long-forgotten Behemoth that clashed with the Leviathan. It acts similar to Elpis’ Telesphorus variation of Bulwark, albeit not retaining the same emphasis on defense. Instead being more direct and using attacks that send water-like waves from the Hayate Buster’s blades. Is good at doing sneak attacks but mistakes when using Rolling Thunder may be very costly in health. Works well with Hayate Busters to shift approach easier. Finishers leave behind afterimages of Volans for sustained damage. Allows Ritsueto to curve shots around obstacles or guide them towards targets with pinpoint accuracy, making it deadly at close and long ranges. It has the capability of altering the molecular structure of whatever they hit through adjusted vectors, leading to creative effects like turning solid objects into liquid or gas. Gains more energy from enemies that are taunted.
Ranged combat for Ritsueto’s Hayate Busters is weaker than Elpis’ PB-Railbuster. Even if it does good against lesser enemies, it cannot fire through walls nor be used as well while moving, but it can aim in multiple directions due to Ritsueto’s trajectory. Firing at enemies up close repels them.

Levi: A sabertoothed wolf-like support droid equipped with a learning optical neuro-AI and was inherited from Volans, whom was able to use a synchronization adapter system to infuse with him via chained plugs. Counters Elpis’ Chiron Strata by being able to transform into a hoverjet titled Yotomoda. Gives a boost from nano-infestant lyciagrotis within his program accumulating. Crystallized data of the rune codes are augmented onto him when using Ex Arms.
Heliusseura: Ritsueto’s symbiotic disc heart in the form of an eldritch fungal flower, it’s crystals being used as mutative power cells. The petals induce bloodclot seeds to appear on himself before converting in Onyx Black-out.
– Trivia –
Ritsueto has a monastic samurai/ninja motif with themes of void. This is opposed to Elpis’ theme of aether while having a spell-casting technological knight motif and the gladiator/spartan motif of an upcoming antagonist.
Ritsueto’s animal motif is a mix of a fish and avian to clash with Elpis’ snake motif
Elpis and Ritsueto share many thematic parallels with each other:
- Elpis is donned in black, Ritsueto wears white
- Elpis is themed after a snake, Ritsueto is themed after a fish
- Elpis is a human who uses cybernetic enhancements powered by atomic energy, Ritsueto is a special organism who uses blackhole-themed abilities mixed with antimatter
Ritsueto was originally a Venom-like character, whom would be humanoid but have a symbiote of Equinox within him that enhances his Swordmaster-like fighting style. He retains a similar background of being a clan but at the time, his lover was going to be Tateteta.
Ritsueto was originally going to have elemental forms.
- Flame coats Ritsueto’s armor in lime with blue streaks, burning plants and puts enemies in constant damage when the status is active. Attacks have a gun trigger-like effect at the end of combos, blasting away enemies. Thrust is with a powerful bursting shot and is strong against enemies to the front. Shots are short-ranged. Has upward attacks, as Ritsueto’s slash combo has an upward slash at the end with more vertical range but less horizontal range. Slashes away bullets and has increased slashing range.
- Lightning coats Ritsueto’s armor in gold with purple streaks, stunning enemies for paralyzing combos. Sends 4 short-ranged homing projectiles sent in zig-zag patterns depending on the enemies near. Enhanced descending slash by pressing downward once more, making a slam that causes huge bolting swords to spring up from the ground. Range is lengthened and speed is high, draining more energy. Has after-images when attacking rapidly. Sends spark currents after performing heavy attacks. Has invulnerable intangibility to all enemies and their attacks for the duration of a shadow dash. becoming temporarily undetectable in it’s duration. Collects more health capsules from increased probability. Has a spell card that sends a large sparking ring either upward or downward. And when hitting the ground, it splits into two bolts crawling around the ground.

- Wood/Wind coats Ritsueto’s armor in lime with orange streaks, ignoring crumbling terrain and absorbing obstacles with light high-speed movement but low damage. Enemies are pushed away in heavy attacks. Can dodge enemies overhead. Has an idle stance that can react to an attack by timed reactions, pushing the enemy back and dashing through them or absorbs shots with spinning sword-shield. Makes short-ranged shockwave from slashing downward at the end of a normal sword combo, which is lowered to two slashes. Shots split. Has a sweeping slide for shield. Slides down walls slower. Shoots a small ball that bounces across walls, with the angle of the shot’s rebound depending on it’s direction when hitting a surface until it self-destructs.
- Poison/Water/Psycho coats Ritsueto’s armor in purple with red streaks. Lowers Ritsueto’s gravity, causing him to take longer to land from jumps. Has a high energy gauge usage of multiplying damage with multiple slash waves, sending phantasmic sword in the form of waves, enhanced descending slash that can be used to 3 times. Can redirect vertical maneuvers multiple times. Can jump off surfaces of water quickly. Healing is raised. Shots travel in a sine wave of low-gravity, spreading out as they fall.
Ritsueto’s health was originally going to be called Will and have health items damaging him as a reference to Specter Knight in Shovel Knight: Specter of Torment.
Ritsueto’s eyes are pale due to underdeveloped mutative materials making him reach to a certain point of adrenaline which he often attempts to exceed with his Vaesir Drive. He has a third eyelid membrane for protection, turned pale from the mutative materials in it.
Drazenith Zetsubou has a form of enchanted writing on it
Ritsueto was originally going to have charge shots like Elpis. This was removed for balancing. The charge shot levels would’ve been;
- Hayate Buster’s first charge conjures a ghostly Volans that is fired at enemies burning them in it’s path. If at full energy and holding the shot after firing, the first charges conjures a barrage of ghost projectiles changing element depending on Ex Arm.
- Hayate Buster’s second charge was never properly thought of
- Hayate Busters’ third charge surrounds Ritsueto with a spiralling wave of four large energy orbs when grounded. But when releasing in mid-air Ritsueto slashes downward with his Hayate Busters, splitting his shot into the energy orbs with each one moving at a diagonal angle.
Ritsueto originally was going to have a harder time parrying with his melee. This was given to Elpis so that his melee has a harder time while Ritsueto is better at parrying via his sword.
Ritsueto’s shoving spell card for Rolling Thunder is a reference to Shun Goku Satsu
Ritsueto’s Drazenith was originally going to be able to be used like a flute as a reference to Tommy Oliver’s Dragon Dagger
Both Ritsueto and Elpis have necklaces tied to their families, Ritsueto carrying a runestone amulet passed in memory of Aheri for him and Isobel while Elpis has an asterisp-smelted pearl pendant shared with him and Lyra that is actually split.
Ritsueto ensuring to never break a promise with Isobel is a reference to the myth Banchō Sarayashiki
Ritsueto’s cloak is formed from substances of Tehom and mothwing strands
Ritsueto has an IQ of 250
