Sakamoto is a stylish student whose cool behavior draws the attention of everyone at his high school. Three punks in his class who don't like him, Acchan, Mario, and Kenken, target him for all sorts of bullying, but it always backfires on them. So they finally decide to take care of him for real...

One day, Sakamoto sees his classmate, Kubota, being shaken down for money. He calls out to him, and Kubota begs for his help, saying he has no money left. But Sakamoto has an idea... Who's the coolest? Sakamoto. Girls compete for him and play Kokkuri-San to find out who he likes. How will it end up?

A second-year delinquent, Maruyama, has been making first-years into his errand boys. Sakamoto becomes one of them, and Maruyama is more than pleased with his work. Eventually he grows bored of coming up with orders and tells Sakamoto to serve him of his own volition!

Every day, Sakamoto arrives at the last possible minute and uses all kinds of tricks to slip through the gate in time. Kakuta-sensei, the guidance counselor, keeps an eye out for Sakamoto at the school gate, but Sakamoto always bests him. Now he's determined to catch Sakamoto!

Sakamoto has permanently scarred Maruyama from when he was his personal errand boy. Hayabusa-senpai, the delinquent and head of the second-years, challenges Sakamoto to a fight!

Sakamoto imparts lessons upon young children playing games each day on their way home from school. Sakamoto is being followed by a poltergeist! Can a classmate who follows Sakamoto around with a camera tell him?

One day finds Acchan, Kenken, and Mario in the video rental store. They have only one goal: to get into the 18+ section, rent their films of choice, and make the leap into watching porn! But the gate that separates them from the adult realm (the curtain to the 18+ section) is thick, and they can't seem to break through. Just then, Sakamoto strolls into the scene!

Sakamoto and the rest of Class 1-2 are preparing for the cultural festival. But some students lack the motivation to work since the class is only setting up a display, leaving the class rep, Fujita, at a loss. Meanwhile, the delinquent boys are having fun preparing for the festival when they're approached by Fukase, a third-year delinquent who frightens even Hayabusa and his gang...

Fujita, Mii-chan, and Kana-chan are eating lunch outside when they see Sakamoto juggling with piping hot meat buns. As they watch him in fascination, Fujita begins to tell the romantic story of her first meeting with Sakamoto, followed by Mii-chan and Kana-chan.

On Christmas night, Sakamoto meets a college guy by chance and ends up being invited to a mixer with three guys and three girls... but Sakamoto doesn't know the first thing about mixers! What sort of cool behavior will he be able to display at his first ever mixer?!

Snow blankets the ground in town for the first time in several years. Sakamoto has never seen accumulated snow before, so Acchan declares he'll teach him how to play in snow, but Sakamoto easily masters everything Acchan tries to teach him. Acchan is frustrated as his attempts to face Sakamoto on even footing fail, so Fukase tells him that if he wants to be on even footing, then he must fight Sakamoto one-on-one...

It's the day of the graduation ceremony. As Sakamoto is giving the farewell address to the third-years, Acchan suddenly storms the stage and attacks him with a bat...
