Gashin bumps into Yuusei and learns that his foster brother has accomplished a great feat. He built an autonomous city for the Japanese people to safely live in. Yuusei asks Gashin to join him and live a normal life, but not everything is as it seems.
One day, we lost our way
and couldn't get home.
Doch eines Tages verirrten wir uns
und fanden nicht mehr heim.
Un día nos perdimos
y no pudimos llegar a casa.
Mais un jour,
Um dia, nos perdemos e não
conseguimos voltar para casa.
