A werewolf comes in...

I would've really appreciated it if they only talked about vampires, I don't really like werewolves especially in vampire dramas because they ruin the theme somehow.
Anyhow, there's another mystery about a werewolf who is most likely Rion's friend Mai but is she really the killer? I don't think so but she definitely has something to do with this mess and that cookies doctor is really suspicious. Plus Suo's hunger for blood makes me think that something bad will happen, Hopefully I will be proved wrong in the next ep...
