Takashi's friends who acts like a cool biker. He became a magician and gained destruction magic. Kazumi Ida is one of Takeshi's friends who is a wannabe biker so he pretends to be a bully around others. Soon after Takeshi was accidentally turned into a magician, Kazumi was revealed that he is one also (after he came on contact Hotaru's magic). He has a distinct trait of talking with an Osaka dialect. Kazumi bullies others to make the impression of a typical "superior delinquent student." It is also shown that he has sister complex. ~!Kazumi Ida and Takashi Nanase appear to be on good terms, and are good friends. Ida was mainly grateful torwards Takeshi, for saving his younger sister from an older man with bad intentions, and always owed him one. This was evident in Episode 04 when Ida urged Takeshi to save Mui Aiba instead of himself who was trapped in a large sum of ice which was going to suffocate and kill him. They work together in fights, and don't seem to quarrel or argue at all.!~ (Source: Wikia)
