In Tokyo, there lived an outcast fifth grader named Honmaru Edojo who is a naughty youngster and one of the most trodden-upon losers in his class.

He is in love with a smart and pretty girl in his class named Iyona Kawai, but is frequently humiliated in front of her thanks to the school's bully, Jabao Jaba, his companion Korekiyo Ryouguchiya and Iyona's mean-spirited friend, Rui Ijigawa.

After a bad day at school and since almost everyone in town hates him for who he is, his misery and negative emotions reach its peak and nearly took its toll on him until he accidentally summons the great wizard, Taruruto.

Later conflicts arise when new students like the narcissistic egotist Tsutomu Harako, and much later the troubled twins, Neeyo and Neezo Zakenja all transfer to Honmaru's school, all while the dark wizard Rivar attempts to eradicate Taruruto to divert the attention of fellow young wizard, Mimora, who is madly in love in Taruruto.
