Haruto Tenjo is Kaito Tenjo's younger brother. Haruto possesses a mysterious and strange power that can create paths to alternate realities.
When Haruto asks Kaito if he is "weird", Kaito simply tells him that he wasn't and he was just suffering from a bad dream. While it is unknown what he meant, he probably said it so that Haruto does not feel worried about what is happening.
Haruto appears to have a split personality. When not using his powers, he tends to act quite vulnerable, usually staying in bed, or looking down at Heartland from the Heartland Tower, wondering why he can't enjoy laughter like the people who attend the Heartland Fairground.
When using his powers, Haruto sadistically laughs at the Astral World's inhabitants' screams, saying that he "needs more screams" as that is what comforts him.
