Tanjiro's Dragon Evolution System (DxD Fanfic)[On Hiatus]

In the final battle against Kibutsuji Muzan, Kamado Tanjiro died along with the Demon Progenitor to make sure his terror ends right then and there. But he didn't expect to be given another chance at life by a mysterious being, only this time, in a different world filled with gods, angels, devils and dragons. Disclaimer... I don't own Kimetsu no Yaiba or Highschool DXD. They belong to their respective authors. This is only a fanfiction.
