Enter our hero Wakadaishou! He doesn't have much interest in school; he saves his energy for all the excitement he can stir up after school. This is an early Adachi Mitsuru 'youth manga', filled with engaging characters, comic scenes, and a young hero with a zest for life.

A collection of three short stories. 1. **Heart no Ace** (ハートのA, Ace of Hearts) Akizuki Akira is the Jaguars' ace, but even he can't beat the Elephants' star player Edajima. When Sakura Misao joins the team it seems like they might have a chance, but Akira can't stand to be shown up by a girl and quits the team. Not one to disturb the peace, Misao leaves the Jaguars to find a new team, but when she finds a spot with the Elephants, who will win the final showdown? 2. **Teens** (ティーンズ) The morning of his first day at a new school, Wakamatsu Jirou accidentally helps capture a dangerous criminal, and rumours spread like wildfire. Now a living legend, he's the first and only line of defense against the delinquents that make everyone's lives miserable. Only problem is, he doesn't know the first thing about fighting! 3. **Aoba ni Kaze** (青葉に風, Fresh Leaves in the Wind) Class 5 wants to win the upcoming girls' softball tournament, but with school idol Yamazaki Misa on class 2's lineup, not even their own male classmates want to cheer for them. When an unathletic yet perceptive student by the name of Mizutani Hiroshi offers his aid as their coach, he might just be the perfect secret weapon.

A boy that lives for baseball. A girl he likes. They watch each other pee and are now connected for life.
