[Defeat]

Anime Title: Zatch Bell!
Genre: Adventure fiction, Comedy, Fantasy
Anime Summary: The goal is to become the Mamodo king which is achieved through battle with other Mamodos and their books being burnt. The title is of the main character who is actually one of the good ones, but there are plenty of evil Mamodos that he faces and others as well. The reasons pretty much vary. "Kiyo Takamine is an apathetic but highly intelligent middle schooler who doesn't fit in very well at school. Most of his classmates are jealous of his genius and annoyed at his stand-offish personality(except Susie who, despite being a total ditz, has a big time crush on Kiyo.) But Kiyo's life takes a major turn when his father, who works at a university in London, sends an extremely hyper-active but good natured boy named Zatch Bell to live with Kiyo. Kiyo's father found Zatch lying unconscious in the woods in London with nothing but a red book with him. However, Zatch has no memories of where he came from, and the words in the red book are written in letters that no one can decipher.

It is a very good show and I've rewatched it multiple times in the past. I recommend
