I've pre-ordered the OP & ED Singles. (Also the first DVD release)
But for now here are my ripped from the series tv sizes:
OP - Spell by Lama -MediaFire-
ED - Rokutō Sei no Yoru by Aimer -MediaFire-
Nezumi's my favourite. I also suspect Sion will dawn his white hair before the end of episode 3. (Officially it's Sion, not Shion, FYI)
edit: just gonna place this link here for future ref. It's some trans from the No.6 novels. *__*
