Disguised villains(not revealed): After exactly the Festival, you finally left UA, leaving no trace behind. You found your team returning to them. And with that, Meta liberation Army arc, AKA MVA arc begins.

Villains in LOV: The beginning of MVA arc.

Villains in MLA: Revival party has begun, the army faces off with LOV.

For heroes and heroes in training: You all celebrating Christmas. Until you came across the commercial of Detnerat, and for some odd reason, uou feel like something's going to happen. A few days passed, the news about Deika City(whete the revival party happened) had been reported. How do you feel about this?

I follow the manga more in this one, cause Seasom 5 skipped a few scenes of MVA. This is honestly my favorute arc, can't stop rereading it. This is obviously around MVA arc.
