Yuuki Sakurai

Miyon's friend from elementary school. Plays the violin and the piano, although he's embarrassed to admit it. He thinks Karin tested into their school and thinks she's very intelligent. He has a power which can make a forbidden ring (at last known as Zeus's Ring) shine in the manga series only. In the Anime, he is just a normal classmate of Karin and Kazune's. He has a crush on Miyon. He has a less important role in the anime, although he has much more important in the manga. In the manga, he holds the hidden power of Zeus, which Kazune thought Michiru held.
