Machine-gun talk without pausing for breath. Speaks as if cornered. His hobby is questioning people. Harsh attitude (especially towards men). Performs tasks dispassionately. Highly curious.

Pupils sometimes dilate (especially when expressionless). Wants to get naked the moment eyes are off him. Says what he thinks immediately without hiding it. Talks to himself a lot.

Talks to himself a lot in his true persona when Toyota and Guest aren't around or are unconscious/asleep. Toyota's things are his things. Hates Toyota.
