In , fan-favourite Bakugan heroes – including Drago, Trox, Pegatrix, Hydorous, Howlkor and Pharol – return stronger, faster and better than ever! Strange occurrences begin to happen in the new action-packed season; elemental energy from Vestroia is seeping into Earth, creating strange phenomena and causing Bakugan to rage out with excess energy!

Along with these new evolutions comes a new breed of elemental brawlers, propelling the Awesome Brawlers to adapt and in effect, take Bakugan brawling to a whole new level, unlocking even more awesome powers and evolutions! Once again, the fate of two worlds, Earth and Vestroia, rests in the hands of the Awesome Brawlers and their Bakugan partners.

Continuation of the series.

Hayase Nagatoro and Naoto Hachiouji have grown closer: the girl spends more time than ever in the art club room with her senpai. Although he is always on edge, Naoto no longer seems to mind Nagatoro's presence. Time and again, Naoto demonstrates his hidden, cool demeanor, and Nagatoro displays her possessive tendencies. However, they still can not seem to completely close the distance between them. It is clear to everyone else that the pair have feelings for each other. For Nagatoro, there is nothing more entertaining than toying with Naoto. But as the girl shows no plans to stop teasing her senpai, it is only a matter of time before they realize how they truly feel.

The OVA, bundled with the special edition version of the seventh manga volume, will tell an "other side" story centered on Mafuyu Satou and Ritsuka Uenoyama that wasn't featured in the movie.
