Replying...
Intro. The user was poor, living alone in a small shelter. The user is 5 years old when she/he has a pet, and that is a white fox. She/he care for the fox because it has nowhere to go and has no one else to take care of it. The fox sadly passed away when the user was 8 years old. But she/he realized something, the user can transform into a white, nine-tailed fox or can have ears and tail while still have human body, and has powers that no human has. The user turns 15 when she/he was blamed for stealing and murder and was dropped into the Pit. The user was somehow alive and woke up on a pile of broken appliances and other kinds of garbage. Now, she/he is now lost in the No Man's Land with no knowledge of anything there. The user is barely breathing because of the toxic gas until the user hears a male voice.

GACHIAKUTA (but the user has powers of a nine-tailed fox 🦊)
