After joining forces with Team RWBY, the group came clean to them about who they really are and where they came from. They also told them of the twisted game between Black Hat and Alastor as well as their mission to stop them. Team RWBY were visibly shocked about what they had heard. 

Ruby: Whoa....there are other worlds out there....

Eda: Yep. I think we broke them....

Jack: I know it must be strange to hear this. Many of us here now are still processing this information. But we intend to stop this madness before it goes too far. 

Yang: Sounds like we're already in a bad way.....

Obi-Wan: It looks like they're going to spread their "champions" across the Multiverse. 

Itachi: Which means we won't have to fight them all at once.

With the rules of the game now revealed, the group pondered their next move. 

Aelita: Okay....we should start by stopping Salem and Aku.

Jack: My Sword is more than equipped to defeat Aku and his minions. 

Goliath: Then that just leaves Salem. 

Ruby: Maybe we can help? 

Alucard: This just got more interesting. 

With that, Team RWBY had joined forces with Aelita and the others in stopping the battle between Salem and Aku. Meanwhile in the center of Atlas, an intense battle broke out between Salem's Grimm and Aku's Minions. 

Salem: Oh poor Aku. What am I going to do with you?

Aku: You cannot hope to win against the might of Aku!

Salem: Foolish Aku. This world isn't yours to conquer. It was never yours to conquer. A smaller, more honest soul. It's true that a simple spark can ignite hope, breathe fire into the hearts of the weary. The ability to derive strength from hope is undoubtedly mankind's greatest attribute... which is why I will focus all of my power to snuff it out. This world will be mine. Try as you wish, Aku. I'm looking forward to watch you burn.

Aku: HA! You claim yourself to be an avatar of evil, but I am AKU, Master of Masters, the Deliverer of Darkness, the Shogun of Sorrow, and the Shapeshifting Master of Darkness! All who stand before Aku are destined to fall!

As the two titans of evil spoke to one another, the group and Team RWBY arrived. Upon seeing Aku, Jack gripped his Sword and called out Aku. 

Jack: AKU!

As Jack called out Aku, the Master Of Darkness turned to Jack with a confused look on his face. 

Aku: Samurai? What are you doing here?! 

Jack: We are here to stop you! 

Aku: Aw, put that thing away, Samurai. We all know what's going to happen. You'll swing your sword, I'll fly away, and probably say something like "I'll be back, samurai!", and then I'll flutter off over the horizon and we won't see each other for about a week, and then we'll start the whole thing all over again. I'm actually busy right now. 

Ruby: Not if we have anything to say about it!

Salem: Time isn't on your side, little one. It has always been mine. 

Alucard: You're beginning to bore me. Let's cut to the chase. We are here to end your little war. 

Without hesitation, Alucard began unloading his Jackal and Casull Pistols on the armies of Salem and Aku. As the battle began, Jack and Obi-Wan began cutting through both the hordes of Grimm and Aku's Minions. Aelita and Eda along with Goliath and Itachi as well as Team RWBY began fighting through the armies of Salem and Aku. During the battle, a Grimm pounced on Eda. As Eda attempts to fight off the Grimm, Aelita uses her Lyoko powers to blast the Grimm away. Aelita then helps Eda up.

Aelita: Are you okay?

Eda: I'll live. Thanks for the save, kid. I owe you one. 

As the battle intensified, the group with help from Team RWBY were able to get close enough to Salem and Aku. It was at this moment that Cinder Fall and the rest of Salem's Cabal joined the fight, but Team RWBY were able Without hesitation, Jack attacks Aku with his Sword. Obi-Wan joins the assault on Aku by gripping him with the Force. On Salem's end, Itachi activates Amateratsu, engulfing Salem with black flames. Alucard proceeds to unload his Jackal and Casull pistols onto Salem. 

Alucard: IS THAT ALL YOU HAVE, DARK QUEEN?! THE NIGHT IS STILL YOUNG! SUMMON UP YOUR FOLLOWERS! 

As Alucard taunts Salem, Salem unleashes a powerful shockwave of magic which blasts back Itachi and Alucard away. At the same time, Aku was able to free himself from Obi-Wan's Force Grip. Aku then transforms into a goat-like creature and charges at Jack and Obi-Wan, but Goliath glides to Aku and holds him back. This allows Jack to slice through the Demon. Eventually, the group were able to subdue both Salem and Aku. But as they were subdued, they were both teleported away. 

Eda: What the hell just happened?!

Alucard: The cowards have scurried away like rats. 

Obi-Wan: I don't think so. I sense that Black Hat and Alastor are to blame for this. 

The group looked around to see neither of Salem's Grimm or Aku's Minions surrounding them. 

Eda: Looks like they cleared the board. Guess that's a score for us. 

Goliath: We may have ended one fight, but the battle ahead is still upon us. 

It was at this point that Team RWBY was about to thank them. But before Team RWBY could thank them, the group was teleported away without a trace. In that moment, the battle between Salem and Aku was over, but the real fight was far from over.
