Iwanami Hiroshi

Blood type: B Hiroshi is a boy from Yuri's class. His hobby is playing the trumpet. He is given an attack alien to put on his head, and gets addicted to it, attacking more than once. [spoiler] Ms. Megumi is the one who gave the boys their aliens to train the girls. This way they would become stronger, and Ms. Megumi would make a good impression to beat the other schools, like school 3. [/spoiler]
