Kazuichi Arai

荒井一市, Pin

Nickname: Pin Height: 1.93 m Weight: 88 kg Bloodtype: B Birthday: July 25 Sign: Leo Life philosophy: "I'm the best" Arai Kazuichi is the temporarily homeroom teacher for the gang's class. He is nicknamed Pin and always is called that way (except Sawako who obeys the formalities and still calls him Arai-sensei). (The previous homeroom teacher had been said to be sick after he made Sawako to do his work during the summer holidays.) He is a great fan of baseball as well as the school baseball team's coach. He used to be part of Kazehaya's father's league team, so he has known Shouta since when he was young. He had once said that he likes to 'interrupt' people. He nicknames Kazehaya and Sawako's found-beside-the-river puppy Pedro Martinez. (Source: Wikipedia)
