S01E10 - More Than the Darkness
Synopsis
Protected by a charm she got from Shun, Saki manages to defeat the Impure Cat before meeting him. Shun reveals to her that his entire village was destroyed because his powers went out of control. She also learns from him that the drastic alteration in the world's fauna and flora seen in the last 1000 years was due to the residual energy that flows from humans whose powers are not in full control, just like it happened with his dog Subaru, who is killed while protecting him from the other Impure Cat, which is subsequently destroyed by Shun. With little time left before he is killed by his own uncontrolled power, Shun reveals to Saki that he always loved her before having her flee to safety.
