After her political father is disgraced in scandal, Haruna Aizawa transfers to a new school...Haruna Aizawa thinks that school life is just like a monkey mountain - all the monkeys form cliques, get into fights, and get back together again. The school that she just transferred to is no exception. There's even a boy called Macharu(baby monkey) Yamashita [ actually named Masaru Yamashita ] who reminds her of a baby monkey!It's hard enough fitting in at a new school while dealing with family problems.... Will Haruna remain jaded and distance herself from everyone around her? Or will Macharu win her over with his monkey magic?
