Gunma-chan, Uncle Akio, Aoma, and Meemi visit Gunma's kofun site and wander into an alternate world beneath Gunma in the Season 2 finale.
We don't have a chance 
against this many people.
Wenn wir gegen so viele kämpfen müssen,
können wir kaum gewinnen!
No podremos contra tanta gente.
No podremos contra tanta gente.
Nos chances sont minces,
contre tant de monde.
Non abbiamo scampo
contro così tante persone!
Contra tantos, nós não temos chance.
Их больше, мы едва ли победим.
