“The Sunshine Underground” is one of my favorite episodes of Eureka Seven. I don’t know how exactly to describe why, but the word I would use to describe “The Sunshine Underground” would be “Atmospheric.” There is a lot happening in this episode. There is a sense of mystery, danger, and confusion throughout, too. All of the characters it, seems, are at crossroads in their literal and figurative journeys.
And I just think the “The Sunshine Underground” is a good name for an episode. It is a name that is open to interpretation.
