"OMOI MI (THE HEAVY SEED)"
Story from: Volume 3, Chapter 3
Summary: In one village, during yearly natural disasters, if a tooth grows in the roof of the mouth of a young woman, it's said to bring good luck for the coming harvest. At the end of the harvest and autumn, the tooth falls out, and the woman dies. Ginko comes to investigate the origins of this horrific ritual, and its ties to the local rice processing industry in the village.
Review: I never did really like this particular story from volume 3, if just for the squick factor. Ugh. Though interestingly enough, it seems like this story has ties once again to the Ikigami/sacrifice factor - girl dies for village's continued good rice harvest for the following year. Still, a bit too gross for my tastes. :/
