Aikawa (会川) is a Magic User and Risu's long-time best friend. Aikawa lived as a third-rank Magic User. Unable to produce enough smoke to use magic, he went to the South Zagan Magical Training School to learn how to use magic and produce more smoke. There he met Risu and teamed up with him to get rid of an abusive teacher. Afterward, they became close friends and partners, at least by word. He lives a happy life with no worries while stealing food from the school's cafeteria and lazing around.
