Summary of Eureka Seven until Episode 26.

A special episode that is a non-canonical alternate ending to the show. The script for this special was first performed in 2006 at a Sony Music Festival by the original Japanese voice actors. In March of 2012, Studio BONES decided to put existing footage of the TV series to this audio and air it for the first time on television.

The Day After is a 2-minute segment that consists of a collection of images that show the aftermath of episode 50. The images cover events of the main characters in the year 12006, a year after the final episode.

Ten years ago, the major earth-shaking “First Summer of Love” event occurred. Renton, who lost his father during the event, now attends the army school of the United Federation of Predgio Towers located in the border town of Bellforest. Because his late father is still praised, Renton feels something is lacking as he continues with his ordinary, boring days. Then one day, Nirvash, the world's oldest LFO, appears in front of him and a girl named Eureka emerges from the cockpit. This was the beginning of the future of humans and Scub Coral, another intelligent lifeform. Was this encounter all just a coincidence? Or was it fate? Where will Renton and Eureka's journey end?
