Yuu's sex partner.

He is a typical nerdy-looking guy with glasses. He is basically a passive person and is not compatible with Yuu, who is a masochist at heart in terms of personality as a sex partner.

His male organ size is quite large, about the size of a Westerner's. Hardness is not so great, this earned him the nickname "sea cucumber cock".

Since he is a passive character, he does not do anything to arouse Yuu's masochistic nature. He is financially well off, and Yuu considers this a benefit for herself.
