2 Nezuko Was 12-Years-Old When She Was Turned Into A Demon While Nezuko slept and Tanjiro trained with Urokodaki at the beginning of the series, two years had passed, which means that, while Tanjiro would go on to turn 15, Nezuko became chronologically 14-years-old, though still technically a 12-year-old. Nezuko Kamado is Demon Slayer: Kimetsu no Yaiba's biggest wild card, a demon who fights alongside Demon Slayers. After being transformed into a demon by Muzan Kibutsuji, the Progenitor of Demons, Nezuko changes the game by refusing to consume human flesh like others of her kind do. Conclusion. Nezuko is easily one of the most powerful demons in the Demon Slayer series, possibly due to the large quantity of blood she was given by Muzan. But what makes her her a truly terrifying opponent is her willpower, being the only other demon after Tamayo to escape Muzan's control. That’s all today guys maybe I’ll make one about eri it’s literally like 3:03 and I typed all of this sooooooo good night ^_^ <3
