In the dead of night, in the most dangerous area in an unknown city, a lone teenage girl walked along the streets... She doesn't know who she is. She doesn't know who she's been searching for. She doesn't know that her whole world will turn upside-down. She only knows that she can finally stop looking for happiness. And maybe, in her new life, she'll find that one friend is actually so much more... THIS IS BASED ONLY ON THE ANIME, AFTER IT ENDS.
