Twinkle * Crusaders GoGo!

Sakura Shin is a hard-luck high school student. One day, he becomes the student council president of Ryuusei Academy, a position which he thought is given free meals from the cafeteria, as he has been raised in a poor family and is in need of money. But his job as president includes getting rid of mazoku (denizens of hell) that appear in his town as well. Also, he is informed that his father was the former Maou (king of demons) and he is supposed to succeed to his position. He has to fight against mazoku as the president but he is the Maou. Well, will he be able to keep it a secret and enjoy his school life?
