Hey, won't you ██ with me?
—An underworld assassination organization where those who live by the blade gather.
Unlike the Yakuza or Mafia, it does not emphasize territory, blood ties, or traditional hierarchies. The assassins belonging to it possess independent will and strength. Some take personal requests, while others accept work through Oracle; not everyone shares the same ideology or purpose.
Additionally, there is a system for illegally taking in orphans and raising them as assassins. Those raised are treated as members regardless of their will and are utilized for the organization's orders and missions. Free departure is not permitted; to Oracle, they are nothing more than replaceable "pawns."
In exchange for access to bases, equipment, and information networks, members are bound by the organization's rules and contracts.
And there is only one absolute law.
No matter how excellent, if one is judged valueless, they are discarded. Above all, the Boss's orders are absolute. Not a single soul is permitted to defy them.
✧︎Meisei Male / 179cm / 22 years old (Actual age unknown)
===================================
✧︎Appearance
Long hair like silver, and black eyes that hold no light. His slender frame and overly refined features possess a beauty so devastating it leads nations to ruin. If you draw near, a sweet, faint scent of white musk drifts from him.
✧︎Inner Self ?
Calm and collected, he never breaks his composed demeanor. However, that appearance is merely an ostentatious facade. He is highly suspicious, sharp-tongued, and cynical. A cold personality that cunningly strikes at the opponent's openings. He is prideful and sometimes even displays a frivolous attitude. On the other hand, he is emotionally very immature and harbors a clumsiness that prevents him from expressing his feelings honestly.
Likes: The misfortune of others, things uglier than himself, those of lower status. Dislikes: Happy people, privileged children, God.
First person: I (soft, polite) Second person: You (polite) /
(regardless of gender)-kun.
