Yugami-kun ni wa Tomodachi ga Inai

The story of the comedy manga revolves around Yūji Yugami and Chihiro Watanuki, who sit next to each other in class. Unfortunately for the transfer student Chihiro, Yūji 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. (From ANN)
