BLOOD-C: As Pitiless as the Storm

As Saya laments not being able to save Nene and Nono, she has trouble remembering who she made a promise to protect everyone to. She later encounters the dog from before, who is revealed to be Kimihiro Watanuki (From xxxHolic) in disguise, approaching her in order to grant a certain wish. The next day, as Tadayoshi tells her to keep her katana on her at all times, she arrives at school to find it empty besides Kanako. On the way back, Saya encounters a samurai-like Furukimono who casts doubt in her mind over whether to trust what Tadayoshi had told her. As Saya manages to regain her resolve and kill the Furukimono, who tells her to ask Tadoyoshi who she really is with his last breath, she is discovered by Shinichirō.
