Kakeru's childhood-friend and classmate, whose charm point is her "antenna" hair which changes form according to her mood. She's an heiress to the Tenkuuji group of companies and she holds a romantic feeling toward Kakeru. She's gentle and easy-going, but her weird sense of imagination tends to warp her into her own world. She became Yell's owner as she bought a sports drink at the night of Yurika Kochikaze's birthday party. She has the history of being saved by Kakeru from being kidnapped. She also gets drunk off from carbonated drinks and will attempt to strip when under the influence.
