Kawaisou na Mina

The sickly girl Mina just reached the end of her short life. Just once did she wish to again meet and exchange words with a certain person, but unfortunately she has turned into a ghost...
A dark and melancholic yet humorous fairytale about a ghost and the people who have to help her find her way.
