"Okay...we've taken out 12 of the 13. Only one left is their leader, Xemnas." Jexi said.
"Since he's their leader, he's the strongest one." Ace said.
"You aren't wrong. It was a long battle against him when we fought on the Organization's world." Sora said.
"Really?" Ajna asked. "How many times did you have to fight him before he finally decided to go down?"
"Well, we fought him in a city first, then he was armored up aboard a giant battleship dragon thing, and then we fought him at full power inside some sort of space." Hope said.
"I gotcha." Ajna said as she looked to the gate. "I'll go. Who wants to join?"
"Okay...I'll join." Asta said.
"Think I better lend my support too." Naofumi said.
The three of them soon entered the final gate. Past it, they entered a strange void with a mix of white and black as Xemnas stood there in a white and black coat. "Vanish, Interdiction." he spoke as his two ethereal blades emerged from his hands.
(Cue- Darkness of the Unknown *Final Xemnas*- KH2)
"Anger and Hate are supreme…" Xemnas said.
Xemnas then started to vanish and appear across the battlefield before getting close to Ajna and attempted to slice off her head before Naofumi stepped in.
"Air Strike Shield!" he called out as the shield blocked the attack.
"Whoa! Thanks, Naofumi!" Ajna said.
"Don't go passing out thanks. Wait till after the battle is over!" Naofumi said.
"Right, right, sorry." Ajna said before she retaliated at Xemnas with an attack of her own. She struck with a double blow from her axe, followed by a spear staff slam and a rising kusarigama slash before finishing with an arrow shot. "Okay!" she cheered, causing the arrow to explode.
Xemnas retaliated by creating an array of lasers as they fired at the three, only for Asta and Naofumi to block them with their own weapons. Xemnas then cast all three of them into darkness as a multitude of lasers surrounded them.
"Shield Prison!" Naofumi said, trapping the three of them in a sphere made of shields as the lasers bombarded it.
"This guy's strong!" Ajna said. "Then again, he wouldn't be the leader of the entire Organization if he wasn't."
"We need to attack him quickly the moment the lasers stop. Only way we can take this guy down." Naofumi said.
"Right. Asta, I'll go high, and you go low." Ajna said.
"Right." Asta said.
The lasers soon stopped firing as the shield prison broke open. It was at that moment that Xemnas grabbed Ajna and tossed her into the air and attempted to strike her, only for Asta to take the hits for her.
Ajna then changed into her Maha Heruka form and slammed down onto Xemnas with her axe, sending him straight down. After turning back, she built up her iddhi more as she changed further into her Tara form, and channeled her inner potential into a powerful axe uppercut, sending him flying into Asta's line of sight. "Black Meteorite that jerk into next week, Asta!"
"Haaa!" Asta called out as he laid down the final strike against Xemnas as he vanished into data. "All right...that did it."
"We won!" Ajna cheered, sharing a hi-five with Asta and Naofumi. "That was some awesome teamwork we pulled off."
"Yeah!" Asta said. "Thanks for watching our backs, Naofumi! You really do live up to being called the Shield Hero."
"It's fine." Naofumi said as they returned to the garden. Upon their return, the ground opened up as rising from a pedestal was a small sphere with the symbol for the Nobodies engraved on it.
"Hmm...Thou hast proved thyself strong against the enemies of the past. In recognition, thou hast claimed Non-existent proof of your accomplishment." Robin read on the pedestal.
"And then there is this sphere. What do you all suppose this could be?" David asked.
"I'm pretty sure that's the Non-existent proof that the pedestal was referring to." Theo said.
"I think so too, it proves we were victorious against the Data Organization XIII." Spade said.
"And yet there was no record of this at the time of the Organization's formation. How very curious." Raine said.
"I'm pretty sure that's why it's called as such, Sage." Cheetah said.
"So that makes another dungeon off the list." Ajna said.
"Yeah...so now...it's time to leave." Kairi said as they left the chasm just as it collapsed.
"Okay...so far we've cleared four dungeons. That's a seventh of the way through." Ristarte said. "Now we need to decide which one to hit up next."
"Hmm… clearing dungeons are great and all, but I think we all can agree we need to hit up a dungeon that's got some treasure inside, right?" Hope asked.
"Hope, this has nothing to do with treasure. It's all about the adventure." Theo said.
"I know, I was just kidding." Hope said.
"Don't joke about treasure." Meowth said.
"Hmm...how about we hit a universe we don't visit all that often?" Jexi suggested.
"Well...what about the Undead Universe? That sounds like fun." Ethox asked.
"Our home Universe huh? I can get behind that." Kagura said.
"Well, we had to visit that place sometime." David said.
"Do not worry. I don't think it's going to be as scary as you think it will be." Nesma said.
"Yeah...though...hard to say what we'll encounter there." Jexi said. "But we'll have fun finding out."
