Few weeks has past after the Nirvasyl Syndrome rampage in Anima city, a new Beastman arrives... well more like washes to the shore. No one knows how, but she is taken hospital. There Shirou and Michiru are called, because new arrival doesn't have IDs. Only thing she has is pendant, which Shirou could pick a scent, but even if the smell is faint, because the water, Shirou recognize the smell, which concerns him.

After that, more new beastman arrive, but they are not for shelter if not for something... or someone else...
