Mizuki Haruyama is a 2nd-year in Hiiragi Academy's acting department and, along with Shuuma, is one of the Idol Unit AQUA and mediated the Snow White showdown. He's gentle-hearted, with a mysterious, more sinister side due to his painful past. When Mizuki was 10 he became friends with a girl named Sana who was known for failing at everything. When she entered Junior High she decided to become an actor at the same time Mizuki entered the entertainment business. Due to her lack of success Sana gave up on her dream. This greatly hurt Mizuki who blamed himself for 'abandoning' Sana, and who'd made her dream his own. Since then they slowly drifted apart, causing Mizuki to lose one of his only true friends. Hime is the first person in a long time that he's shown interest in becoming friends with as she greatly resembles Sana. As of lately Mizuki has begun to question himself about his feelings towards Hime. He shows jealousy whenever Hime and Senri are together even going so far as to make sure Hime doesn't get near him. As of chapter 52, he realized that he is actually in love with Hime. He belongs with GGC Production and one of the two(except Senri)that was informed by Director Yamada that Hime is actually Shiro to help her in her further work. At the near end, he says he needs to work harder and become more mature so that Hime might even come to fall in love with him later.
