Eureka Seven

As Eureka's mysterious illness persists, a United Federation Fleet is approaching the Gekko. The cause of her illness is suspected to be due to being close to the mines. For some unknown reason, though, Eureka decides to take the Amita Drive from the Nirvash, causing it to go into the depths of the mines with Eureka inside. This leads to Renton going after her, without ever realizing the tragedy that awaits.
