Lumi used to be a devil. She used to be Ạ̸̏k̵̩̉ú̸͜j̶̪͒i̴͉̐. She hated the devil ways and attempted to fly up to heaven, only to fall when she didn't know there was a barrier preventing devils to get through. She fell unconscious after landing in a cave-like area, but her fall was cushioned by soft yellow flowers. When she woke up, her wings were... angelic.
