Episodes 31-34: These have to be the most enjoyable and probably best episodes of the series so far. Episode 32 was great, and the mecha action was amazing. Things are starting to make more sense after revealing that this planet is not Earth. The pacing is very good with calm after high tension.
Episodes 35-38: I really enjoy when Eureka Seven is able to nicely combine drama and high tension with calmess and a bit of comedy. I finally learned something about the enigmatic Diane and Adroc. Episode 38 was great. I love how a misunderstanding between Renton and Eureka led to questions on sexuality and the meaning of family. I rarely see anime that abords how young and old people deal with sexuality and its consequences, good and bad. I feel proud of myself because I anticipated that Dewey had seduced the female sage, Koda.
