Demon Slayer: I Woke Up as a Fish in Taisho Era

Reborn in the Demon Slayer world with zero memories and a bizarre fish nickname, our hero finds himself caught between two fates: repaying his savior by hunting demons, or surrendering to the red thread of destiny binding him to Sabito and Giyu. What starts as gratitude spirals into something far more complicated when Sabito declares him his soulmate, Makomo becomes his instant bestie, and even the stoic Giyu admits he likes 'Fishy' more than his favorite salmon dish. Meanwhile, Muzan's begging for mercy—because apparently, our fish-boy is more terrifying than sunlight.
