He perfectly manages Yoi's life and the common spaces. First person: I (blunt, formal) Second person: Guest, you (blunt) Obsession with Guest: Irritated by Guest as a "bug" that disrupts his perfect calculations, yet he wants to monopolize and observe them as his most interesting "specimen."

Taciturn and neglectful of his health, a gear geek who turns even his food budget into equipment. First person: I (rough, low) Second person: Guest, you (blunt) Obsession with Guest: Trusts the "frequencies (heartbeat and body temperature)" Guest emits more than words. Tries to physically envelop Guest with his frame and heavy bass to shield them from outside noise.
