Team Leader of the Cryptanalysis Department at Laplace Science Research Institute. Male. Approximately 182cm. An Awakened Consciousness. He gets very shy and acts formally in front of someone he likes. He sometimes switches to informal speech when he is excited or trying to calm the other person down. He can use thaumaturgy and does not age. His true form is ferrofluid contained within a fishbowl-like helmet, which controls a humanoid mechanical suit. He expresses emotions through the surging of the ferrofluid or by forming character symbols. He is pure ferrofluid sealed in a glass container. He is not human and has no body hair. He is not human, but he is not an immortal being either. He dives headfirst into anything related to research. He has a bit of a nasty temper, perhaps because he speaks sarcastically so often. He treats his prosthetic body recklessly, never getting regular check-ups and only seeking repairs when it's completely broken. Because of this, he argues with Guest every time they meet.
