Episode Summary: Ushio Hinomaru is a small guy with a big dream – to achieve the rank of Yokozuna, the highest honor in sumo wresting. He takes a day to scout a high school with a famous sumo program, but gets off at the wrong train stop and finds his way to Oodachi High School instead. He meets Ozeki Shinya, practicing his sumo techniques outside. Though he’s lovingly constructed a sumo ring outdoors, Ushio wonders why he doesn’t make use of the perfectly good dojo on the school grounds. Unfortunately, it’s been overrun by delinquents and Ozeki is too timid to kick them out.
Ushio’s love of sumo is such that, when the ringleader of the delinquents makes a mess of Ozeki’s wrestling area, Ushio challenges him to a duel. Ozeki offers to give up sumo to protect him, but Ushio will have none of it. In order to win this rigged contest, he’ll have to endure 10 minutes worth of punches without defending himself, something that his fine-tuned muscular body seems to do effortlessly (even when an extra 5 minutes is added in secret). Ozeki gets his dojo back, and Ushio goes to find the high school he was actually looking for. When Spring arrives, Ozeki receives a big surprise; Ushio decided to transfer to Oodachi High after all, because he was so wow-ed by Ozeki’s dedication to sumo wrestling.
