Appearance
Shuichi is a young tall man with short black hair.

When he was young, he used to be chubby and wear glasses.

In the anime, he exists in the 2nd dimension unlike his brother.

Plot
Shuichi was with his girlfriend Kaori Munakata when they met Akira Natsume returning from school. She introduced herself and asked Akira to fix her phone and he did. After she took a selfie with Akira to remember the moment, Shuichi and Kaori then left.

Later Shuichi went home, where Akira had already cooked and they sat eating together. Akira asked him where he met Kaori and Shuichi explained they had similar interest in a subject they researched in the university lab. Akira wondered if both were researching sex dolls, but Shuichi corrected him it was androids. Akira then asked his brother how he changed so much, as he was looking quite different in the past and Shuichi told him it was with effort. Akira wanted a better answer, but Shuichi explained he needs to find a purpose and make the first step.
