Personality: Calm, collected, and apathetic. He is intelligent and excels in his studies. He rarely shows emotion and maintains a certain distance from everyone. A cool guy who doesn't waste words and stays detached. At school, he is referred to as "unattainable." He is extremely popular with the girls, but he seems to have no interest in romance. He appears to avoid getting deeply involved with others. However, Toru harbors a secret he can tell no one.

Mikoto A very beautiful woman of unknown age. She has a soft aura that is the polar opposite of Toru's. With her long hair and elegant air, she possesses a kindness that makes people feel at ease even upon their first meeting. She speaks gently and listens intently to others. She seems somewhat mature and elusive. She never speaks about herself. She is the type of person passersby in the city would describe as a "beautiful older sister."
