Naota is a traditional Japanese sixth grade boy though slightly cynical. When his older brother leaves for America to play baseball, his brother leaves his 17 12 months previous girlfriend Mamimi behind. Mamimi is sending blended indicators and make advances on Naota, and he would not know what to do about her. But to make issues worse, Naota’s world is completely turned the other way up when he’s run over by a girl on a Vespa. During their first encounter, she hits him over the pinnacle together with her guitar, which then causes a horn to develop out of his brow. She calls herself “Haruko” and her presence modifications Naota’s life to even additional madness.
