Naruto Shippuuden Episode 123

[The Chancellor]

there were shadows, but faces didn't have much of them, usually just from hair. the shape of their face didn't seem to cause any shadows, making them look really flat.

I like this animation. They keep hiring these people and they should keep it that way. I don't which animation house does the animation now, but it looks great. It's simple and quick and the lack of detail makes it unique imho. The hidan kakuzu fight is when I most recently remember this style. That's when I started getting back into the anime.

Does anyone know the production house that does this animation?

Edit:
Or maybe once and while they use this animation as a treat for us.
