Masamune-kun's Revenge (Seasons 1–2)

Masamune-kun's Revenge (政宗くんのリベンジ, 2017) is a Japanese romantic comedy anime you can watch online on iFILM. Years ago, Makabe Masamune was a chubby kid who got brutally shot down by the wealthy, sharp-tongued Adagaki Aki. He spent years remaking himself — lost the weight, changed his name, became the school's most popular guy — and transferred back into her life with one goal.

The plan: make Aki fall for him, then reject her just as coldly. Simple enough. Except every scheme Masamune runs into her walls, her secrets, and his own growing confusion about what he actually wants. Voiced by Natsuki Hanae and Ayaka Ohashi, directed by Yushi Abe and a rotating creative team at Silver Link.

What makes this series more fun than its premise suggests is how relentlessly it undercuts the revenge fantasy — the schemer keeps getting outplayed, and the target is never quite what she seems. Stream Masamune-kun's Revenge (2017) online on iFILM.
