Douluo Dalu: Reborn as the Flame Hashira, the Purgatory Flame Never Dies

[A Douluo I fanfic, with an added backstory for Evil Soul Masters] [Sides with Spirit Hall] [Please help suggest characters and Martial Souls that could be corrupted] After dying in battle against Akaza, Rengoku woke up to find himself in a place called Douluo Dalu.

But this new world was already tainted by the presence of demons.

It turned out that a hundred years ago, Akaza had transmigrated here. He had even sought to use demonic power to corrupt Evil Soul Masters, hoping to create a new Twelve Kizuki and resurrect himself through reincarnation.

To foil Akaza's plot to be reborn in this world and find a way home, Rengoku, the Flame Hashira, used Flame Breathing as the foundation to rebuild the Demon Slayer Corps and set out to eradicate the demons!

“I am the Flame Hashira. Flame Breathing, Rengoku: the flame will never die!”
