Takuma is a quiet boy who lives in Lovely Hills. He is misunderstood and often bullied by his fellow townsfolk who believe he's the "Devil's Child," much like Ai was in her village.
When he first made his appearance, his mother was killed by a friend of his father, who was also seriously injured in the incident. As the murderer was about to kill Takuma, he was sent to hell; but at this moment the police arrive, and the townsfolk end up thinking that Takuma is the murderer.
It is unclear if he possesses as much spiritual powers as Ai, but he does have the ability of foresight and he has been observed by Ai for some time throughout the story. In the end, Ai saves him from the townsfolk, but ends up getting killed herself.
