Izayoi Sakamaki is a young boy with strong psychic powers (Esper). He is always bored since no one can challenge him until he is summoned to the world of Little Garden.
Years ago, Sakamaki started a game called "Try to find me" where he would pay someone if they found him. He would go on a rampage as the world was too boring for him. Canaria, Sakamaki's adoptive mother, discovered him 3 minutes before the time limit. She made him admit defeat then proposed that she was going to host a game with him. If she won, she would gain a son, if Sakamaki won, she would play with him for the rest of her life and even provide a wonderful place for him. With this, they both went around the world for 2 years, until Canaria made an orphan institution to help children like Sakamaki.
