This is one of the few mangas I would buy, if it ever came out to NA. This series is one that is full of moments that will keep you on the edge of your seat and warm your heart at different moments. The story and characters are what define this series best. What appears to be a simple slice of life series about girls living on campus, is quickly revealed to be much darker. This is one of the best survival series I've read next to 7 seeds, highly recommended
