Untitled Episode 3

Yui begins to notice how different the Mukami's are from the Sakamaki's. The Mukami's go to school, but they won't let Yui go because the Sakamaki's also go there. They leave Azusa in the mansion to monitor Yui for the day. Azusa invites Yui to his room to show off his knife collection, but things go haywire when he requests her to help him test out the sharpness of one of his knives.
