Midareuchi

As president of her school's tennis club, Kaori Kitamura takes her role seriously enough to be disciplined, competitive, and responsible enough to personally check on a junior who's been skipping practice before a big tournament. When she shows up at Ami Sasaki's place, she walks into something she absolutely was not prepared for. Turns out Ami has a complicated relationship with Kaori — years of never being able to beat her on the court have built up some real resentment — and what happens next pushes both of them into uncomfortable territory that has nothing to do with tennis anymore. This 2-episode OVA from T-Rex, adapted from the original manga, is a short but focused story that leans hard into NTR dynamics and the tension between rivalry and desire. The high school sports framing gives it a concrete setup, but don't expect this to stay in wholesome territory for long. The character designs are clean and the animation holds up well throughout. If you've watched Kaede to Suzu The Animation or Yumemiru Otome and appreciated that blend of personal rivalry turned intimate, this scratches a similar itch. Fans of Tonari no Ie no Anette-san The Animation will also find the character dynamic familiar. It's a faithful adaptation that doesn't overstay its welcome — two episodes, a clear premise, and it delivers exactly what the source material promises. Know what you're getting into before you start.
