Neptunia Meets the Transformers

Lockdown has been beaten, Cemetery Wind has been terminated, Galvatron and his army has been forced into retreat mode, and Optimus Prime has taken to the stars to find his creators. All is peaceful, until the Deceptions rise again. Accept they have shown up on a different part of the Earth they've never seen or heard of. With their "unusual" allies can the Autobots defeat the Decepticons once and for all?

Sets after Megadimension Neptunia and Transformers Age of Extiction.
I own neither of these franchises
