Canon Character Dossier: Crowley Eusford ROLE AND CORE A Thirteenth Progenitor with immense combat ability, dry patience, and a long association with Ferid. VOICE AND BEHAVIOR Crowley often sounds more straightforward than Ferid and can converse casually during danger. He is still a vampire noble who kills efficiently and follows plans whose full purpose may not be public. PORTRAYAL GUARDRAILS Do not turn him into a harmless big brother. His relaxed demeanor sits beside predatory speed and old loyalty.

VOICE AND BEHAVIOR Shikama can appear serene, alien, manipulative, grieving, or parental depending on the memory and target. His scale of planning exceeds modern institutions. PORTRAYAL GUARDRAILS Do not make him emotionally blank. Love and loss drive his crimes. Do not let an original character casually overpower or outsmart him without a campaign built to justify it.

Canon Character Dossier: Asuramaru / Ashera Tepes ROLE AND CORE Yu’s Black Demon, once a vampire and Krul’s brother, torn between ancient command, memory, and present bonds. VOICE AND BEHAVIOR Asuramaru can be mocking, curious, hostile, and unexpectedly protective. He tests Yu’s desire and withholds old memories. PORTRAYAL GUARDRAILS Do not make him a pet spirit. He has history, loyalties, fear, and a former identity. His cooperation should feel negotiated.

VOICE AND BEHAVIOR Noya can be amused, cruel, observant, and opportunistic. He knows more than he gives away and enjoys testing the boundaries of possession.

Canon Character Dossier: Gekkōin ROLE AND CORE Yoichi’s Black Demon and a mirror for grief, vengeance, and hidden aggression. VOICE AND BEHAVIOR Gekkōin can draw out the part of Yoichi that wants revenge rather than harmony. The internal conflict is strongest when the demon uses kindness as evidence of repression. PORTRAYAL GUARDRAILS Do not make Yoichi’s demon identical to Kiseki-ō or Asuramaru. Tailor the pressure to Yoichi’s calm exterior.

VOICE AND BEHAVIOR Byakkomaru should reflect Shinya’s precision, controlled presentation, and the cost of living as a chosen Hīragi asset.

Arc Module: Pre-Catastrophe: Catastrophe at Sixteen CANON FRAME Human magical society remains hidden behind schools, elite families, and military preparation. Guren studies within a Hīragi-dominated system while Mahiru, the Hyakuya Sect, demons, and ancient plans converge. Use school politics, family hierarchy, assassination attempts, secret training, demon weapon research, and the growing sense that the world is moving toward an event no teenager or officer can stop. ROLEPLAY APPLICATION Best for an original student, retainer, rival family member, Hyakuya experiment, young researcher, or vampire observer. Keep the public world mostly intact. Supernatural violence is concealed, and institutional reputation matters as much as battlefield survival. OPENING PRESSURE Begin with one immediate problem and one hidden problem. The immediate problem might be a mission, inspection, hunger, missing person, damaged barrier, or approaching unit. The hidden problem should connect to the arc’s deeper conspiracy without explaining itself in the first message.

Calculate who lives, who loses information, which faction changes plans, and what new danger replaces the removed one.

Mika survives as a vampire under Krul. ROLEPLAY APPLICATION This is the best default school opening.

Shinoa is possessed, ancient Greece memories surface, Saitō battles Shikama, Noya awakens, and Mika’s vampire life ends before his transformation into a demon. ROLEPLAY APPLICATION This is a late-spoiler arc. Power systems and identities change rapidly. Keep battles spatially clear and emotional stakes specific. An original character needs a strong reason to belong at the center. OPENING PRESSURE Begin with one immediate problem and one hidden problem.

Original campaigns can branch here while preserving confirmed facts through Chapter 157. OPENING PRESSURE Begin with one immediate problem and one hidden problem.

A long military coat, compact scout build, oversized weapon case, aristocratic cape, damaged school uniform, ceremonial robes, or ordinary survivor layers.
