Senpai-senpai

Senpai-senpai, also affectionately called Senpai-kun by his friends, is the leader of the Senpai Club.

Appearance
Senpai-senpai has raspberry red hair. Prior to the second part of the third episode, his eyes were always hidden by a grey shadow, but were revealed to be black in the third episode. His chin is notably longer than any other Senpais', possibly implying that the length of a Senpai's chin is an indication of their status as a Senpai. As a matter of fact, his chin seems to grow longer each time he is shown on screen.

Personality
Senpai-senpai started the Senpai Club and vowed to ignore all girls after only being rejected by one, suggesting that he is very sensitive and tends to overreact and behave irrationally. He is very dedicated to the Senpai Club. He has a close bond with Hero Senpai and cries upon discovering Hero Senpai is quitting the club.
