So this episode of Gurren Lagann was AD'd by Takashi Mukouda, one of the best animators in the industry. He redrew pretty much majority of the cuts in the episode, so his presence is pretty much everywhere. If you haven't, please check out his works uploaded to booru, he's a phenomenal animator... currently working on Haikyuu!! so please keep an eye out for him.
