I would've liked the anime to go into the Yotsuba clan in more detail and show the reminiscing of the past. In the final episode of the anime, I wanted more action. It was kind of anti-climatic when he just used Material Burst with the Third Eye and BOOM...it was all gone. TWICE! =_=" Oh well, it was still quite a good ending. Better than some of the ones which just completely kill the anime off. 8/10 for the last episode, in my opinion.
