When I Went to Another World, My Little Sister Was Already Reigning as the Demon Lord

異世界行ったら、すでに妹が魔王として君臨していた話。

Makoto is suddenly summoned to a magical world, where he finally reunites with his little sister Misaki, who vanished two years ago. To his shock, she is now reigning as the Demon Lord of her own kingdom, commanding armies and ruling with an iron fist.

Though Misaki treats him like a pet and bosses him around, Makoto sees through her tyrannical facade. Behind the fearsome Demon Lord is still the same lost and lonely little girl he remembers. Now, he must navigate this strange world while trying to protect and reconnect with his sister, all while dealing with the chaos her rule has caused.
