Konjiki no Gash!! Kanzenban

Kiyo is a brilliant junior high student whose inflated ego (and tendency to blow the grading curve) has made him a major target for teasing at school. So his father sends him a bizarre birthday present – a strange little boy named Zatch Bell – to help him make friends and reform his bad attitude. Zatch brings with him a mysterious red volume of spells, and Kiyo discovers that Zatch has magic powers that are unleashed by reading from the book! But there are more surprises to come, and Kiyo's destiny is about to change forever!
