Cast: KADA Michiru

Strange things are happening all over town, and Kouichi's nightmares have started again. Several clans have been spurred into action as the past gradually resurfaces. Just what is going on, and how do the Amano brothers fit into the picture? 

Summary from Storm in Heaven:

Last year, Taichi nearly died on a snowy mountain, but was saved by his best friend, Shinobu. The only problem is that Taichi doesn't remember a thing about this so-called childhood friend of his! Assuming his memories will return, Taichi keeps this little secret to himself until, a year later, he suddenly finds himself with a much bigger secret. You see, Shinobu is more than he seems, and Taichi might not have actually survived that night on the snowy mountain!
