College pro-wrestling is not much more than flashy costumes and staged matches, but law student Igarashi is eager to join the sorry university team. A scrawny and awkward fellow who's always scribbling notes and snapping photos, Igarashi has plenty of heart, but he's slow on the uptake. Nevertheless, he soon makes his ring debut in lizard-masked glory as Gachi Boy. During his first "match", he forgets the choreographed moves and clumsily improvises instead, a big safety no-no in college pro-wrestling. But Igarashi's dogged fighting spirit turns him into an unexpected crowd hit, enough so that the college association comes knocking. Finally, the team has a chance to join the league and prove their worth, and everything is riding on the slow-learning Igarashi. What the team doesn't know, however, is that Igarashi actually suffers from short-term memory loss. Everyday when he wakes up, he has no recollection of the day before.
