The main character and ace of the Kamihoshi baseball team, he is the first person Chihiro meets when she transfers into Kamihoshi. He tends to do things at his own pace, always marching to the beat of his own drum. He is notoriously known as a troublesome weirdo amongst not only his baseball club teammates, but also his classmates and this causes him to be isolated by his peers. However, being alone doesn't faze Yuuji at all, and he claims he doesn't need friends.

Koki Uchiyama is a Japanese actor and voice actor from Saitama Prefecture affiliated with Himawari Theatre Group.

The story of the comedy manga revolves around Yuuji Yugami and Chihiro Watanuki, who sit next to each other in class. Unfortunately for Chihiro the transfer student, Yuuji is weird... extremely weird. Even though he's the ace of the baseball club, he hasn't adapted to the club at all. He also stands apart from the rest of the class, but seems completely satisfied with being alone.
