The first we actually see Tsubaki Mahiru is actually awake for it. I mean he comes to collect Belkia after all.
Too much insane is just that too much. I'm slightly concerned they intend to shove too much into too few episodes. I've read up to vol 5. Some of the characters shown on the credits have either just been introduced by the end of vol 5 or haven't yet so. worry.
OLDCODEX's OP 'Deal With' features screaming. I'm not a screaming fan. at all. I've notice they are going that why more. It's unfortunate.
The ED is better. Sung by Terashima (Mahiru). The OP animation also sucks but don't worry the rest looks normal.
