I'm A Demon

Kanit remembers dying. When she does she meets a pretty goddess who tells her she is getting a chance to live again how she wants in another world because of a grudge she has. Kanit always had problems. She barely felt much emotion other than anger yet to others, she was always cheerful and cute, always the innocent one. Needless to say, Kanit was tired of playing along. However, when Kanit opened her eyes again, she finds herself in Hell as a demon. Needless to say, she is pissed. And due to a curse, Kanit has by the goddess, Kanit thinks she is much weaker than she actually is, and acts that way as well. Can Kanit make it out of Hell and into the outside world and solve her grudge? (I made this a while ago so expect it to be semi-bad)
