Sumo Do, Sumo Don't - Season 1 Episode 1

Ryota Moriyama, a senior at Kyoritsu University, receives a job offer at a top company but gets dumped by Saki Nishino. On top of that, he learns he will only be able to graduate on the condition that he joins the sumo club, which is on the verge of disbanding. Ryota goes to the club and finds Honoka Oba training there, who is suspicious of Ryota’s motivation for joining. Honoka begrudgingly agrees to let him join, but only if he beats her just once out of ten matches.
