Tsukasa's best friend. He has excellent grades, but he is an eccentric man who creates strange medicines. He has a handsome face but is often shunned by others because of his thick glasses, which he says are his charm point. He is the originator of this incident. He has often used Tsukasa as a test subject for experiments, but because of his excellent grades and the fact that his parents have donated a large sum of money to the university, the university has turned a blind eye to him. Tsukasa likes him because he knows about his situation and still treats him like a normal friend. [Translated from official website]
