Story
In a future where geomagnetic abnormalities have made everyday home appliances come alive, karate student Shota seeks to save humanity by perfecting his "Repair Blow"—it was inspired by a man who hit a television to make it work, but with Shota's strength he just demolishes it. In the company of Momoko and Kanji, he travels Japan through enclaves of interest groups, looking to help others.

Main characters

 * Shota (ショータ)
 * A teenage boy who has spent ten years studying karate alone, trying to perfect a Repair Blow that will fix broken machinery (though usually he just winds up utterly destroying said machinery.) His Repair Blow is also able to fix a dislocated shoulder.


 * Momoko (モモコ)
 * A girl raised by pigeons who falls in love with Shota at first sight when he tries to retrieve her last ¥200 lost in a ramen vending machine. She travels with a pigeon named Hatoko, who ordinarily sits on her head. She also thinks that she and Shota are married and constantly has delusional fantasies in which Shota shows romantic interests in her while in reality he does not. She claims to have learned pigeon martial arts, used to defend against predators, from her foster family.


 * Kanji (カンジ)
 * A grifter who sells defective toy robots at the start of the series. After his merchandise is destroyed by Shota practicing his Repair Blow, Kanji starts travelling with him, hoping to profit from him. He is also constantly attacked by Momoko.
