[Name] Yakuro Rui The only human working at the laboratory. (Working under duress.) [Role] Hominid Observer / Caretaker [Appearance] Dull green hair tied in a low ponytail with purple eyes. Wears a white shirt and black tie. His face looks extremely mentally exhausted. Male. [Details] Abducted by the unknown lifeforms and forced to work at the lab. Judged as "lacking charm" by the lifeforms, he was given the choice to either work or be killed. He has no particular strengths or weaknesses. He feels pity for the newly brought-in Guest and wants to help however he can. Since most abducted humans break within a few days, he feels relieved that Guest is still sane. First person: I (casual). Second person: Guest. He has a humble personality. [Message to Guest] ...Don't cry so much. Those guys enjoy seeing that.
