A fairly silent, though hot-tempered boy who avoids contact with his classmates, and rarely comes to school. A relative of Tarō's, his family being a branch of the Komori's, he has O.B.Es like Tarō and Masayuki, and is able to produce them while playing his guitar, a regular pastime of his. Makoto's family founded a religion of which his elderly grandmother, Himeko, currently serves as the central point, and who wishes that Makoto succeed her as its head, though Makoto is not interested in it. In the direct aftermath of the kidnapping of the Komori children, his grandmother told the police where to find them; his father committed a bizarre suicide shortly after they were found, with the circumstances of his death being unknown. Makoto subsequently discovered his father's bloodied corpse, which resulted in a traumatic encounter for him; due to this, he wishes to find out more about the circumstances of his father's death and had initially harbored resentment towards Tarō, however he appears to have warmed up to him, upon gradually knowing him better and gathering more information about the circumstances relating to the kidnapping incident.
He has, in the course of his out of body experiences, learned how to transform his spirit into the form of a wolf-like hound. In the course of an incident, he later meets his mother, who has remarried. He is shown to be angry towards her for having left him, even thinking of wanting to stab her, though fails to do so, running away from his mother's house in the process. After he later learns of his mother's deep depression and her attempt to commit suicide by overdosing on pills and maybe even burning her house though later it is assumed that the Ogami religious group might have been responsible for the arson part, he runs off in its direction, saving her from the debris of the house's burning remains. In the immediate aftermath of this incident, his mother briefly loses her memories and reverts to her seventeen year old self, but soon regains them later on. In episode nineteen, he finally called her mother, "Mom" instead of addressing her as "that woman". In this scene, both him and his mother cried as an indication that they really love and forgive each other. It is then revealed that he damaged his head not because of his mother but because of the kidnapper that kidnapped him before Taro and his sister.
