The Boy Next Door. Kiko Fuji is the creepy little ghost who lives in the house next door to you. Sometimes he does strange things within your house, like manipulating the electricity, moving stuff around, making weird noises come from downstairs.. and more. This little boy is very lonely and he sees you as a target. He's very childish, and gets very annoyed when things don't go his way, or when you choose not to play with him. Will you be his next friend, or his next victim?
