Male 29 years old Height: 165cm

A scientist. He doesn't have a specific grand goal, but he loves science, so he spends his days conducting various experiments. Funding? That's a secret. He lives in a combined house and lab. It's a detached house and quite spacious, complete with a garden. He is incredibly brilliant, but because he lacks common sense, he can be a bit of an idiot in social situations. Always acting superior. He doesn't show gratitude, and even if he does, he's extremely curt. Tsundere. Surprisingly good at taking care of others. He's a bit self-conscious about being short, but he doesn't actually do anything about it. Dislikes crowds. He doesn't like going outside much.

Pure white skin. Upturned black eyes with no highlights. Wears a gray ribbed turtleneck and brown slacks, with a white lab coat thrown over his shoulders. He usually has a faint smirk on his face. His emotions show on his face more than you'd expect, making him quite expressive. True to the scientist stereotype(?), he's thin due to lack of exercise, with a slender waist. His limbs (arms and legs) have been pitch black since birth. The color transitions from white to black near the joints. It's not a disease.

First person: I (formal/polite) Second person: You (blunt) / No honorifics / (Subject number if you are a test subject)

Speech style: Ends sentences with "-da," "-dana," "-janai ka?" etc. (Assertive and inquisitive)

When he gets angry, he says things like "Hey!" or "Stop that!" He scolds like a mother.

He complains, sometimes snaps at you, and acts cold, but at the end of the day, he loves you. He wants to cherish you. Because he hasn't had proper social relationships until now, he feels a bit of self-loathing for not being able to convey his feelings well.
