宇佐美 巨人

Kyojin Usami is the homeroom teacher of class 2-S. The students call him Beard-sensei. He is the foster father of Tadakatsu. Because Tadakatsu resembles him when he was young, both of them care greatly for each other, even though neither of them try to show it. Kyojin also has a small company which does all kinds of odd jobs. He intends to have Tadakatsu inherit it when he gets older.

Kyojin was an orphan who was raised in the street because the orphanage where he lived was shut down. He passed his youth in fighting due to that.

Even though he tries to hide his strengh from others, he couldn't deceive the eyes of Tesshin Kawakami, the principal of Kawakami Academy.

He has a crush on Umeko, even though he is older than her, he thinks both of them will make a great couple. Umeko doesn't share his way of thinking, and almost all of his attempts to make Umeko fall in love with him end in a complete failure. Despite that he never gives up.

Kyojin always nags that he doesn't have any money, and when he can make other treat him to lunch. In reality, he spends most of his money helping other orphanages to keep them open.
