The Angel Pillar

This story is about my Oc based off of the anime " Demon Slayer " her name is Akarii Shinazugawa, she is the younger sister of Sanemi Shinazugawa and Genya Shinazugawa, she became a demon slayer after her siblings and mother got killed by demons, her mother turned into a demon and almost killed her, she ran away with Genya when Sanemi protected her and Genya from her mother who was a demon. After Sanemi killed they're mother Genya and Akarii were shocked, Genya hated Sanemi after that, But Akarii didnt think it was Sanemi's fault since they're Mother could have killed them. Years later After Sanemi became the wind pillar Akarii started training to become a demonslayer along side her brother, she made up her own breathing technique called " Angel Breathing " another few years later she was 14 years old, and she had became the Angel pillar along side her brother Sanemi as the wind pillar, Genya didn't start training until about 3 years after Akarii started her training so he wasn't a Pillar yet.
