Kazuichi Arai

Resumen

__Height:__ 193 cm Arai Kazuichi is the temporary homeroom teacher for the gang's class. He is nicknamed Pin and always is called that way (except [Sawako](https://anilist.co/character/6977/Kuronuma-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 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 [Shouta Kazehaya](https://anilist.co/character/13531/Kazehaya-Shouta)'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.
