"Who are you?" NIGHTS demanded at the twins.

"We are Gemini, the twin ninja workers of Wizeman", they answered.

"I am Castor", the black one said.

"And I am Pollux", said the grayish silver one.

JEEPERS! I've heard about this two! Corvus exclaimed. "They're deadly and dangerous, but all I've known was these guys were in slumber."

"Master awoke us because he ordered us to take the visitor's ideyas and to bring back the traitor" Castor said without a motion.

"These guys actually lack emotions", Gavin thought.

"Do not try to escape us", Pollux said to them. "Or else the visitors will get hurt."

"And what makes you think we'll allow that to happen?" NIGHTS said stepping in front of Aza.

"NIGHTS these two are like shadows, if somebody gave them an order, they'll obey it and if you try to fight them but it was not given as an order, your attacks will on face through on their body. It will only came into effect on the people they were ordered to fight", Corvus explained.

"Then since Wizeman said to bring me back in Nightmare, then I'm not going anywhere without a fight", NIGHTS said.

"Unfortunately you are mistaken", Castor said as he pulled out his sword." Our first order was to get the visitor's ideya. We will deal with you later."

"If these guys want a fight, then we'll give them a fight", Gavin said as he cracked his fingers. "My sister and can handle this."

Are you sure you two can handle this? Corvus said. I mean, Aza can't fully control her powers, right?

"That was before, but now I can", Aza said without any fear. Thou she knew that sometimes she can't. She's still at practice.

"Pathetic visitors", Pollux sneered at them. "Do you think you have any match for us?"

"Yes we do!" They both said." If we win, you'll let us leave. But if you win, you can take our ideyas."

"It's a deal", replied Gemini.

"I hope they know what they're doing", Owl said in a worry.

Aza and Gavin stepped into the battle field and created their own weapons.

"Shadow make! Gun blade!" Gavin commanded. A sword then suddenly appeared in his hand, it was like to combination of sword and gun.

"Shadow make! Naginata!" Aza commanded. A long metal like staff with a long blade on top appeared in her hand.

"Ready for combat?" Gemini asked.

"Ready as we'll ever be", they replied.

The fight was on. Gavin battled Castor while Aza battled Pollux. Pollux's weapon was a long katana that pierced even the hardest rock making it hard for Aza to evade.

"You two are skilled swordsmen", Castor commented on them. "You should join us. We could use someone like you."

"Nah, were good", Gavin said as dodge an attack." Besides, we fight for what we think is right."

As the battle went on, Gemini and the twins were fierce on their battle. The two nightmaren never thought that a visitor could match them.

"I never thought that this two could be so good", NIGHTS said to Corvus.

"Well since they were on the circus after the war, it's only natural for them for them to adapt on what they learned", Corvus said.

"But still, they are children", Owl reminded them.

It looks like Gemini seems to be in a lot of damage and so was the twins, but they were still ready to fight no matter what.

Finally Castor pleaded to them." Stop, we yield! We yield!" And also at the same moment, Pollux also surrendered." We admit our defeat, you won."

Alright they won! Cheered NIGHTS." I knew they would make it."

But as Aza and Gavin turned to leave, Gemini then attacked them with their powerful attack.

HEARTLESS ANGEL!

A beam was shot at them. Gavin pushed his sister away and also did his powerful shadow attack.

SHADOW VOID!

A portal then suddenly opened and absorbed Gemini's attack, causing it to bounce back at them but only with stronger force. And with a flash, the Gemini twins were gone. Gavin stumbled back after his attack.

"Big brother!" Aza cried. She then ran to him and so did their companions.

"Hang in there buddy! You're going to be okay" Corvus said trying not to panic.

"No I'm not going to be ok", Gavin said as he was gasping out of breath." I did my most powerful shadow move. But my body wasn't fully prepared for it."

"Is there something we can do?" NIGHTS asked feeling extremely worried not just for Gavin but also for Aza.

"No there's nothing you can do for me now. My attack diminished all my energy."

Aza then began to notice that Gavin's body was slowly disappearing; she began crying as she clung into him.

"No big brother! You can't leave me again", Aza cried.

"Don't worry little sis", Gavin said as he smiled through his tears. "I may be gone from this world, but we will meet again someday in our world. I may not know when, but I know someday we will."

"We lost each other once. And now were losing each other again."

Gavin wiped away the tears in her eyes and said he never got to say while they were together.

"Little sis, promise me that matter how far we may be apart. Just remember every day and night, I am wit and here with you by spirit, you are not alone. And always be strong. No matter what happens."

Gavin then stared up in the grey sky and said." You know the best part of my day is?"

Aza shook her head.

"I get to see my little sister all turn into a beautiful and brave girl and meet a few friends who we can trust. Little sis, I love you."

"I promise that big brother", Aza said in tears." I love you too."

And at last, Gavin's body disappeared completely. Aza couldn't bear it so she cried even harder. NIGHTS did his best to console her telling that Gavin's wish was for her to stay strong and remember that she was not alone. He dried her tears and showed his deep sympathy to her. And at the same moment, she received the yellow and white ideya that appeared right after Gavin defeated Gemini. After that, they all returned to the dream gate, thinking their next move.
