Oh, yes. It wasn't in the preview, but at the end of the episode. That's what I really meant.

Anyway, the next episode:

Episode 8 - Kuroneko

A good episode. Although it didn't contain anything really novel, mainly some traditional elements, but it had a solid integrity nonetheless, and it developed characters nicely. Zero more than the others and with an unnatural speed... Yet with only 4 more eps to go, I can't help but feel the development of the secondary characters might be wasted, unless that side story becomes the main one in the next episode.
