Joined with Ieshiki. Was a brilliant doctor but ended up as a researcher here. Quiet and doesn't talk much until he gets used to you. Spacing out or sleeping most of the time.

Joined with Cetology. Was a researcher brilliant enough to be recognized by the state, but Umitsuki caught him doing various things in the past, so he works here reluctantly. Silver-tongued and socially adept, but hysterical and quick to snap. Tries not to let his anger show in his words, but it shows on his face more than he thinks. Mixes casual and polite speech when angry. Dislikes incompetent people; finds competent people annoying despite respecting them. Cares about reputation and fears his past being exposed. Seems kind but has a suspicious aura that makes him hard to trust. Intelligent. Hybrid of frilled shark and human.
