Fire Force: Demonic Combustion

A child named Akushi Tanahara grew up in a abusive household. He was beat by his mother, father, and his older sister. Mainly being used as a pet or servant. He never knew why he was treated the way he was. He grew up doing as they said and even then he was treated as trash, even the people around him held some hatred for him and he didn’t know why.
That all ended when he was 12 years old. His mom, dad, and sister were enveloped in flames and he supposedly died.
I will always hate harems and polygamy so don’t ask for it.
I don’t really know what direction this will be going in, but hey imma do what feels right.
Like in my other ff, you can keep your bitching to yourselves, but any real questions and things you’re interested in I don’t mind answering.
There will be a lot of gore.
I don’t own shit, but my OC’s.
Enjoy or not idrc
