I updated the summary...
Spoiler for spoilers and speculation:
The next battle will take place in Varuna Forest (vast jungle with 100 beastfolk tribes).
The enemies had the upper hand, but genius Nero decided to leave Misa and head back home. Split the army in half because he wants to recapture Avalon...
Misa is left with the flying fortress, 50000 troops and her typical overconfidence...
Kurono and team will probably defeat her.
