Life gets pretty boring when you can beat the snot out of any villain with just one punch. Nothing about Saitama passes the eyeball test when it comes to superheroes, from his lifeless expression to his bald head to his unimpressive physique. However, this average-looking guy has a not-so-average problem--he just can't seem to find an opponent strong enough to take on! Garo goes up against the giant insect Centisennin! Centisennin targets the rescue helicopter carrying Tareo and Sekingar, but then Metal Bat, who is pursuing Garo, appears! Can Garo and Metal Bat work together to take down the monstrous insect?
