Lemme know whatcha think. NISA's sets are so beautiful. I have Bunny Drop and Demon Prince Enma Burning Up. As far as Katanagatari, I'm on the fence. so I can't wait to hear your thoughts.
I'll post more in the "currently watching" section when I have time but knowing your love for anime I would be surprised if you didn't love this title. I posted screen captures and gifs on my site (they're not mine so I can't take credit).
