Haruki's childhood friend.  He is a first-year sociology student at Meishiin University and a member of the male cheerleading club, Breakers. Before Kazuma's parents died, they were amazing cheerleaders. Wanting to make them proud, Kazuma once given the opportunity decided to start his own cheer club, leading us to where we are now. He also has a sick grandmother with memory loss, and while he cares for her deeply, seeing her lose more and more of her memories takes a toll on Kazuma.
