Yuuna

Yuuna is one of Kitti's classmates and probably the most important of the side characters, since she is a member of the team to stop Naoki. She has a cute and bubbly personality and seems to enjoy talking about boys. She also seems to be very openminded and imaginative, since she takes a liking to Chance's imaginary friend Mana-chan. Her twin brother, Yuuma, has a personality quite opposite to hers, but they are probably quite close to each other, since she once suggested him to perhaps be the handsomest person in the school. Both twins are close friends with Yuzuki.
