阿部 零士

One of Bango's childhood friends and Mariya's older brother. He is also Bango's classmate and best friend at the same time. When Mariya started high school, they moved back to Mina-Asakusa. A very calm, logical and smart boy who however lacks a sense of humor because of his ability, and has a hard time smiling at all. He often talks in weird phrases that neither he himself or an ordinary person can understand at all. His ability, "Meisou Shinkou (Meditation Chromatic)" gives him advanced memory and cognitive abilities.
