The Cat Who Ruined My Isekai

Yuta Hayashi, a 17-year-old high school student and die-hard otaku, lives under the domestic tyranny of his white cat, Ren, an arrogant feline who scratches him at the slightest unauthorized caress and reigns as the absolute master of the house. But when a mysterious magic circle appears beneath their feet, they are both thrust into a medieval fantasy world. The shock is twofold: not only does Yuta realize he has just been isekai’d, but Ren has transformed into a naked man with cat ears—and he has become overpowered. Absolutely. Completely. Absurdly overpowered. ​Physique: infinite. Mana: infinite. Speed: the speed of light. Abilities: all of those available in this world. ​As for Yuta, he inherits a pathetic power of invisibility limited to two measly minutes per day. The master-servant hierarchy has not been reversed; it has worsened. Now accompanied by a grumpy elf guard with a murky past, the unlikely duo embarks on a rescue mission—to find a missing princess—that will lead them straight into the terrifying Black Forest, territory of the beast-folk. But in this game of deception where every side manipulates the other, is the princess really a victim? Who is truly pulling the strings? And why is Ren, that insufferable cat with a galactic ego, deliberately hiding his true nature? ​Between epic battles, biting punchlines, and explosive revelations, Yuta will discover that in this world, appearances are as deceptive as a purring cat… and that perfection incarnate might just have a few little secrets of its own. > Warning: This story contains strong language and mixes two types of humor: absurd humor and occasional dark humor.
