Episode 20:
Theyre too op, dont like it at all. If the guy can finish one of the 12 this easily, whats stopping him from easy victory? :/ And the breathing is dumb. I can see how breathing relates to sword slashes. But he just stood there and the threads kept bouncing off his skin. So breathing gives you a shield? Uhuh ....
The flashback was boring, nobody needed that. It was obvious from the beginnung why a demon would create family members.
Lastly, I hate the whole "cute girl acting cute, but is actually a capable killer".
