An action comedy about a freshman who joins his university's cheerleading squad and gradually discovers his manliness through interactions with powerful seniors.

“Get them all – girls, school credits, money – without an effort!" These are the rumors that freshman Hachirota Kawachi heard about the pep squad; his reasons for instant enrollment. Hachirota may fall a few screws short of a hardware store, but when it comes to yakuza ties, he has plenty. He is the direct descendant and heir to the notorious Akushin-kai gang. Although this was enough information to keep the pep squad seniors quiet, it’s not quite enough for Aota.

Life in the pep squad is all about harsh discipline. Seniors are "Gods", juniors are "Humans", sophomores are "Slaves" and freshmen are treated like "Trash". One sunny day, two freshmen are entrusted with the task to dry out the squadron's flag; the most cherished and symbolic item of the squad. When they accidentally burn a hole in the flag with a cigarette, they blame Aota. Aota attempts to take full responsibility by committing "harakiri", but changes his mind during the process – a deep stab to the stomach has inspired him with a better idea.
