The story is about some children at least ten who participated in a TV show about espers. Some are true espers and some are not. The main story begin like ten years after when one of them died. The MC, a guy ,and a girl start an investigation in order to find who want to kill them and why. Both are former participant of the TV show. I remember the MC control electricity but furthermore the electricity in the body.
