Konjiki no Gash Bell!!

Brilliant but isolated student Kiyomaro Takamine receives an unexpected visitor from his father: Gash, a mysterious child carrying a red book. Kiyomaro discovers that reading its spells releases Gash's powers and that the boy is one of the children from another world competing to become their next king.

Each contestant needs a human partner, and losing a spellbook to fire means elimination. Through battles and alliances, Kiyomaro begins learning to trust other people, while Gash seeks a way to combine strength with compassion in a contest that repeatedly forces friends and rivals into conflict.
