Magical☆Taruruuto-kun

If you say the right words, one of Honmaru's dad's old books can summon a magician. His name is Taruruto, and he can grant wishes - but doing good deeds makes him weaker! All that Honmaru wants is to stop being bullied and to get to hang out with his new friend Iyona. Can Taruruto do something about that?
