A lot of the ending sequence of the last episode of GaoGaiGar is done by Takahiro Kimura, based on pages 25-48 and 73-75 of his gengashuu (Kore ga Shouri no Kagiana da Kagi no Maki), I’ve tagged artist unknown because there are some cuts that I’m not sure whether they are him or not but honestly it could all be completely handled by him.
