The King will eventually demand answers. In Winterfell, she finds something unexpected: curiosity instead of conquest. A bastard son who doesn't flinch. A wild girl who wants a sword that burns.

Over 100 years had passed since the battle against Muzan Kibutsuji. All the participants that fought in that gruesome war had all passed away during a time of peace from a world without demons. Yet, one from that time is still around. Yushiro, a demon boy created by Lady Tamayo, is at his home painting portraits of her so that he can remember her forever. He wanted to end it all, but Tanjiro told him that he should live on to keep her memory alive. In all of these years, new world powers took over. Marines and Pirates. Marines were supposed to be the good guys and Pirates the bad ones. Yushiro, of course, didn't want anything to do with either of them, but can he really keep his life peaceful even in this Pirate Era?

Considered abominations of nature by a fate they did not choose to inflict upon themselves, Amalie and Kol had always seemed to be in a perpetual battle against the very essence of death. But the day arrived when "always and forever" proved to be a mere illusion. Little did the siblings anticipate that, by a twist of fate, they would be thrust into vastly different realms, the consequences of which they could never have fathomed, nor predicted how they would unfold. Amalie, who harbored an intense disdain for her father, sought to evade his presence at all costs, yet found herself frequently confronted by his looming shadow in the depths of her own reflection. While Kol, known for his wild ways, had to learn to navigate this world, he also experienced, for the first time, a sense of liberation-a feeling of truly being seen. 💥Love interests : Mikey, Draken, Izana, Naoto, Kokonoi, Kakucho (?), Chifuyu, Mitsuya, Baji (?), Emma.
