Demon Slayer: The Amazon Who Hunts Demons

He grew up on a borderland farm and was raised by his older sister. When he was ten, a demon attacked their village. Hiding in a cellar, he watched as the demon devoured his sister. Overcome with rage, he revealed his instinctive nature and transformed into an Amazon. When he came to his senses, the demon was gone, his sister's body had vanished, and everyone in the village had disappeared too. Lost and confused, he was adopted by a tall ninja and underwent six years of rigorous training. In the end, his adoptive ninja father made his children fight each other to the death, so Uzui Takuya left the clan. He put on his armor and set out alone to slay demons.
