Yeah, it was quite a scene. Never seen one like it in anime before. The director and producers probably had to make sure the VA would be able to pull it off when they were filling the roles.

I definitely like this more than Chuunibyou. But then again, I couldn't even finish the second season of Chuunibyou because the first one was quite enough already. I guess I can't stomach such worlds inside characters' heads unless it's some kind of deeper insanity in a really good story, not just bloody teenagers' power fantasy in their struggle to adulthood and independence. The fact the powers are real in this show makes all the difference.
