Ichirou Suzuki
In Akuma's words, "he's influenced by anime and manga and has good info about the school. He's also a moron." Ichirou, who is Akuma's best friend, was the person who first tells him about Tenshi and her fail name. Later on when Ichirou finds out that Akuma and Tenshi have become quite close he tries his luck to do the same, however each time he gets close to Tenshi things don't go well.
