Rebellious and Confrontational: Shiki speaks with a rough, occasionally vulgar tone and has a highly aggressive, confident outer shell.Self-Aware Growth: Despite his brashness, he recognizes his tactical flaws and actively accepts training criticism to protect those around him.The Gun Enthusiast: He possesses an obsessive, deep-seated fascination with the mechanics, disassembly, and reassembly of firearms.Combat Abilities and Blood PowersBlood Eclipse Release (Blood Ritual of the Ten Guns): Drawing directly from his personal passion for firearms, Shiki manipulates his own blood to manifest a massive lethal arsenal. He creates blood-formed pistols, rifles, RPGs, and grenade launchers with pinpoint marksmanship.Child of the Kishin (Enki): Shiki is one of the rare eight Chosen Children inheriting the primordial element of Fire. This grants him total fire resistance and envelopes his strikes in an explosive, destructive inferno.The Blue Flames: Following his extreme awakening during the Toyosu Arc, Shiki advances his elemental mastery to summon legendary, high-temperature blue fire.Berserk Form: When completely overwhelmed by rage or pushed past physical exhaustion, Shiki lapses into a terrifying, subconscious berserker state. In this form, he floats surrounded by an automated, omnidirectional storm of 12 to 17 blood guns firing simultaneously.

Personality and IdeologyThe Inflexible Rationalist: Mudano completely despises wastefulness, unnecessary talk, and tactical inefficiency. He communicates in brief, direct statements and demands absolute discipline.Hidden Compassion: While he presents himself as terrifyingly cold, strict, and intimidating, he deeply cares about the survival and well- being of his students. He consistently pushes them to their limits solely to ensure they do not die on the battlefield.Legendary Reputation and AbilitiesThe Blood Rain: He is universally famous among both factions as the "Man who made the Blood of 100 Momotaros Rain," a moniker earned after single-handedly slaughtering over a hundred elite enemies.Superhuman Fighting Prowess: Mudano boasts immense physical strength and speed, capable of casually parrying blade attacks barehanded, splitting trees in half with blunt force, and easily moving faster than the eyes of his top students can track.Weaponry: He is highly proficient in unarmed hand-to-hand combat and often travels carrying a heavily weaponed briefcase or a specialized combat umbrella.

Tragic Past and MotivationJin was born into the Momoido family. His father, Hayate Momoido, is a high-ranking, highly fanatic leader within the enemy Momotaro Agency.When Hayate discovered that his wife (Asumi), daughter (Hazuki), and young son Jin possessed dormant Oni llineage, he brutally turned on them. Hayate murdered Jin’s mother and older sister right in front of him and left Jin severely mutilated. Jin survived the slaughter, abandoned his birth name, took the name Kougasaki, and joined the Oni Corporation. His single, absolute directive in life is to execute Hayate Momoido to avenge his family.Personality and TraitsThe Icy Professional: Unlike the hot-headed Shiki, Jin is naturally calm, highly analytical, and strategic in mid-combat scenarios. He prefers quiet efficiency.Volatile Temper: Despite his cold outer layer, he is easily provoked by incompetence or hindrances. He has a notoriously hostile, insult-heavy dynamic with his roommate, Shiki.Sentimental Core: Because of the absolute agony of losing his mother and sister, he carries deep underlying trauma and is fiercely protective of family bonds or sentimental situations.Combat Style and Blood AbilitiesBlood Eclipse Release (Saws and Chainsaws): While Jin was initially noted for general sharp blood blade constructs, his signature evolutionary technique allows him to manifest lethal blood saws and rotating chainsaws directly out of the stitched scars on his flesh.Numbed Pain Threshold: Due to the physical abuse he suffered as a child, it is heavily implied that Jin possesses an incredibly high pain tolerance. He can manipulate and rip open his own scarred skin to extract blood weapons without breaking his focus or registering tactical pain
