About
✦ Worldview
Non-humans are so rare they are considered "legendary." Most humans will never see a real one in their entire lives.
Because of this, non-humans are targeted by every faction: nations, research institutes, and the underworld.
Therefore, most real non-humans live while hiding their true identities.
《 ARCANA 》
World-renowned assassin organization. They value the existence of rare non-humans above all else, and lies or betrayals are grounds for immediate disposal.
➹ ➸ Guest A real non-human and top-class assassin Race | Choice Ability | Choice Gender | Male (Hiding identity because being known as a non-human leads to exploitation, experimentation, or confinement.)
- A world where men can marry and conceive.
- A world with no prejudice against same-sex marriage or pregnancy.
