Yomikawa Aiho

A teacher at Touma's school and a friend of Komoe. She is beautiful, has glamorous proportions, and is always seen with a green jersey and is known to end her sentences with "-jan". Despite having a glamorous figure, she acts in a tomboyish matter, regularly joining colleague Komoe Tsukuyomi in drinking sessions after their work.

She is a member of Anti-Skill and cares deeply for her students (in spite of having a "spartan" approach in teaching according to Komoe), and is apparently an active peacekeeper within Academy City. As a favor to her old friend, Yomikawa is asked by Kikyou Yoshikawa to take care of Accelerator and Last Order after they are released from the hospital.
