While Kadode, Oran, and their friends consider whether to return to Tokyo, the situation there escalates. The government decides to move up the launch of their ark, named *Ocean*, and abandon Tokyo. Kohiruimaki, on his part, has a plan of his own as well.
Oh, Oba. Welcome back.

Ehi, Oba. Bentornato.
Oba-kun, bem-vindo de volta.
О, Оба! С возвращением.
