Ayakashi contains episodes 1-12. This is the first ever release in the US.

One summer night in their childhood, best friends Yuu, Hime and Izumi witnessed anomalous, delightful snow. Little did they know that the “snowflakes” carried otherworldly parasites that bond with children and unbalanced adults, granting them wild card powers along with a debilitating curse. Years later, Yuu and Hime are high school students. Their friend Izumi died under mysterious circumstances two years earlier, an event which led to Yuu becoming the neighborhood pariah. He has psychokinetic powers that are just emerging when an unhinged school bully with deadly, developed powers of his own attacks Yuu and Hime after school. They're saved by Eimu, a new girl who is cold yet oddly familiar. She becomes Yuu's friend, mentor, and protector, helping him learn about the Ayakashi parasites that inhabit their bodies and the secret war that's going on because of them. As super-powered assassins arrive, it's do or die for Yuu.
