I Got a Cheat Skill in Another World and Became Unrivaled in the Real World, Too (Seasons 1–2)

I Got a Cheat Skill in Another World and Became Unrivaled in the Real World, Too (異世界でチート能力を手にした俺は、現実世界をも無双する, 2023) is a Japanese isekai fantasy anime you can watch online on iFILM. Yuuya Tenjou spent his school years as the class target — bullied relentlessly, ignored at home — with only his grandfather in his corner. When his grandfather passes, Yuuya moves into the old house and stumbles on a door in the storeroom that opens onto another world entirely.

That world runs on stats and magic, and Yuuya's numbers climb so fast he becomes untouchable. The twist: the portal goes both ways. Skills and physical gains carry over, and the kid who could barely show up to school starts cutting a very different figure back in everyday Japan. Yoshitsugu Matsuoka — Kirito from Sword Art Online — voices Yuuya.

Thirteen episodes, one season, and a straightforward power fantasy built around someone who really did need a win. If the isekai loop of dungeon grinding plus real-world payoff is what you're after, this delivers without much detour. Stream all episodes online on iFILM.
