Marisa comes across a mysterious hermit outside the Human Village. However, as she tells Reimu about her, the hermit is seen sneaking around the Hakurei Shrine. She's Ibara Kasen, a strange, bandaged ascetic of unknown nature and ability who's far more aware of them and Gensoukyou than either realizes.
