"Argh! Kuso!" Sheath said.

"I agree with you, Sheath. It's difficult navigating through the labyrinth like this. But I feel someone misusing the power of the moon close by, two in fact." Tsuki said.

"Since the Sun is setting that would explain it." Corona added as they heard sounds of fighting taking place nearby.

"I sense trouble desu." Sheath said as they saw Kairi and Lea going against Saix and the hooded fighter.

"They're in trouble, let's go!" Tsuki said as the three hurried to them before the door sealed off behind the three. "Kairi, Lea!"

"Tsuki, Corona, Sheath!" Kairi noticed as Lea was pushed back by Saix.

"Nice to see ya." Lea said.

"Thought you could use some help against moon man and mystery person, yes?" Sheath said as she pulled out her sword case weapon.

"Let's heat things up!" Corona said as the floating orb on his forehead shined.

(Cue- A Fight to the Death- Kingdom Hearts 2)

"Surge, Lunatic." Saix said as he wielded his claymore as it became sharper. "Moon, shinedown!" Saix said entering his berserker state as the moon gave him power.

The hooded figure did the same as they summoned the same weapon and executed the same attacks.

"We gotta deplete his power!" Lea said.

"Time to turn the tables, Crescent Harken!" Tsuki called as she summoned her duel scythe as it had an acidic green hue to it as she struck Saix, instantly nullifying his power.

The hooded figure immediately took action as they rushed the group separating them and giving enough time for Saix to recover.

"I call on the Moon's Pale Light!" Saix said charging up.

"Stop it! Just STOP!" Lea called as he attacked with his chakrams only for it to have no effect as he was knocked to the ground as the hooded figure pointed their keyblade at him.

"Axel...I'm...I'm sorry." they said raising their blade.

"Please...that's enough...Xion." Tsuki said as she stood in front of Lea.

"But...how do you know my name?" she asked.

"Hope told me. You don't have to do this." Tsuki said pulling her Keyblade down. "You, Axel, and Roxas are best friends."

"But… Roxas, he's gone!" Xion said. "It was all my fault…"

"Sheath lost… who girl?" Sheath asked.

(Cue- Vector to the Heavens- Kingdom Hearts 3)

"But Roxas can have a second chance just like you! His heart is inside Sora's! It's alright, you can stop now!" Tsuki said.

"Shut up!" Xion said crying as Saix looked down on her.

"A useless puppet." he said knocking her aside as her hood fell down as she fell to the ground.

"Xion!" Lea called.

"You remember?" Xion asked Lea.

"Yeah, both you and Roxas." Lea said.

"Here." Tsuki said as she helped Xion up only to be knocked aside by Saix.

"Enough." he said raising his claymore once more. But before he could strike, a ray of light shined down as a figure blocked the attack. Standing there was a person wielding two keyblades at once.

"Leave my friends alone." he said.

"Roxas…" Lea said smiling.

"He's here." Tsuki said happily.

"This is... Impossible. How are you here? Where did you find a vessel?" Saix asked.

"Most of the organization...originally came here from the past as hearts. But for me...I had help from people you used to know. And those who worked against you." Roxas said.

"Ansem the Wise, Zexion...Vexen and Demyx." Saix realized.

"Vexen was willing to atone for his misdeeds, so he entrusted Demyx to find a replica vessel." Roxas said.

"That's right… no one suspect Demyx to betray organization." Sheath said.

"Demyx would procure a vessel of a replica for me, and then Zexion…. Or rather Ienzo, worked with Ansem the Wise's research to construct the way to it." Roxas said. "But there was one more thing I needed to return."

"And what was that?" Saix asked.

"Sora." Tsuki said.

"I left his heart...when I felt theirs in pain." Roxas said. "Seems Xemnas isn't as good as winning people's hearts as he thought."

"Then I'll just have to destroy you all in his place!" Saix said.

"Kairi, Lea, let Roxas and Xion fight in your place, we'll handle things from here." Corona said.

"Right. When it comes to Keyblades, Roxas and Xion are the old hands." Lea said.

"Corona, I think it's time we used, 'that'." Tsuki said.

"Right… it's finally time." Corona said. "Apollomon!"

"Dianamon!" Tsuki said.

"DNA Digivolve to…!" they called as they fused together into the entity from the New Republic. "Grace Novamon!"

"It doesn't matter what form you take, the end result will still be the same." Saix said.

"It will change, since Xion and I are here." Roxas said. "Brighten and Blacken! Oathkeeper and Oblivion!"

"Shine bright! Kingdom Key!" Xion called.

"Fall, All of you!" Saix said as he summoned multiple claymores in berserk state and attacked.

"The Moon falls...and the Sun rises!" Grace Novamon called as the sun shined bright in the sky.

"What?! Impossible!" Saix said as his power faded.

"Whoa… didn't know they could do that." Lea said.

"We are the God and Goddess of the Sun and Moon, we are capable of controlling and changing the power of the Celestial Stars." Grace Novamon said.

"That's.. Not possible." Saix struggled.

"Xion, now!" Roxas said as he struck with Oathkeeper and Oblivion, cross slashing Saix.

"Haaaaah, yah!" Xion said following up with a quick strike.

"With this attack, this battle's over." Grace Novamon said. "Calydon Arcus!" They called as they fired the eight Meleagros blades on their back flew towards Saix and slashed through him multiple times.

"Gh…" Saix said collapsing as his claymore disappeared.

"Isa!" Lea said running over.

"Why… so sad?" Saix asked. "And here I thought you had outgrown those marks under your eyes."

"I thought you were doing this all for her?" Lea asked.

"I...had lost my purpose. You were the one who went off to make new friends. Leaving me and her behind in the dust. It infuriated me how you just exited our lives." Saix said.

"I...I didn't forget you." Lea said.

"I know. I know you wouldn't do that. But...I was jealous." Saix said.

"You admitted it." Lea said surprised.

"If I make it back, you won't get it out of me a second time." Saix said.

"See you, Isa." Lea said.

"See you, Lea." Saix said before fading away completely.

Grace Novamon glowed brightly as they were split back into Tsuki and Corona.

"Why don't you three take a breather while the four of us go on ahead?" Tsuki said. "It feels like you all have a lot of catching up to do." she said as she, Corona, Sheath, and Kairi ran on ahead with the door sealing shut.

Xion was just crying as the two looked over.

"Heh….guess I should have brought some ice cream." Lea said before the three of them joined in a group embrace as tears fell from their faces.

"(You've kept your promise, Sora.)" Tsuki thought.
