Isekai Slayer(Tanjiro x Tensura x So I'm a Spider, so what?)

After finally defeating Muzan Kibutsuji, Tanjiro Kamado believed his long battle was over...but fate had other plans. He awakens in a dark, unfamiliar cave, not as a human, but reborn as a Dragonoid in a completely different world. A world ruled by monsters, skills, and reincarnations. There, he meets others who shared a similar fate: the kind-hearted blue slime Rimuru Tempest(Satoru Mikami), the ever-evolving spider Shiraori(Kumoko / Hiiro Wakaba), Shizue Izawa, and many more. With no demons to hunt, no breathing forms to rely on, and a new monstrous body to understand, Tanjiro must redefine what it means to protect others. Join Rimuru and Shiraori in the growing Tempest Federation, he begins a new journey, one filled with powerful beings like Veldora, Milim Nava, Luminous Valentine, and the other legendary figures of this world. In the land where strength is everything and fate is rewritten constantly, Tanjiro must ask himself: Does he follow his past path...or create a completely new one? This time, he's not just a demon slayer, he's something far more. Only Tanjiro can decide what his next life truly means.
