Wataru is an ordinary, eleven-year-old kid whose world has just collapsed around him. His father has walked out on the family and his mother is in the hospital for attempted suicide. All he wants now is his old secure and comfortable life back. When a new student at his school tells him he can change his destiny by entering a magic gateway to another world called "Vision", Wataru literally leaps at the opportunity. All he needs to do is collect five magic gemstones that will lead him to the Tower of Fortune, and there he'll be granted any wish. But this is no playful treasure hunt and Wataru quickly realizes that he'll need to summon every ounce of bravery in his 11-year-old mind and body to meet the physical and mental challenges that lie ahead. Before he can save his family, he'll need to do battle with a world of demons, his own friends and, ultimately, himself!
