Disclaimer: I do not own anything of Tsubasa Chronicle, Tokyo Babylon, X, Card Captor Sakura, or any other works, which I might use - all worlds and characters belong to CLAMP; I am just using them to play out some of my speculations.

Warning: Plenty of speculation based on the mind screwy twists and questions which Tsubasa Chronicle and xxxHOLIC left behind.

THANK YOU FOR READING "THE OTHER TWIN"!!!

"Fuuka Shourai!"

With Syaoran's magic, the group was able to go to the castle safely. Once there, they entered the ominous looking castle, but a foreboding feeling made Kamui shiver. Something bad was going to happen, he could sense it.

They stopped in front of a tall pair of doors. The air of oppressiveness that the regal doors exuded made Kamui's stomach twist, but he kept a straight face, like his companions did.

Fai pushed the door open, revealing what was inside.

"Welcome back, Fai."

A sole young man wearing royal robes stood in the middle of the large hall on front of a pool. The raven black hair, long and silky, framed what seemed to be a kind face.

Wondering how the mage would react, Kamui's eyes drifted to his fellow vampire who had averting his gaze. "... I thought I'd be able to not return, if possible, Ashura-ou," said Fai.

"Even though you promised that you'd grant my wish?" Ashura smiled kindly, but his kindness had a chilling air to it. "I've been waiting for you," he continued, while slowly lifting his cloak. "This child... has also been waiting... for you... all the time."

Underneath his cloak, a dehydrated and malnourished child with long blond hair, clothed in rags, and covered in dirt, was revealed. Despite the horrendous appearance, upon closer look, Kamui found that this child resembled someone very closely: he resembled Fai.

Suddenly, flashes of a repressed past appeared in front of Kamui's eyes. A past of twins with blond hair like blessed little angels. But the two young princes were not angels, and were not here to bless their people; no, they were a curse. And as such, they needed to be imprisoned, locked far away, in the above and the below.

This was Fai's past, Kamui realized. Fai had a twin... named Fai? Fai was not Fai. Fai was... Yuui.

"You took the name of this dead child as your own and erased your name from this world. But, even if this is so, your sins cannot be erased," said Ashura-ou, his voice breaking through the flashes of the past, bringing them back to reality. "It's alright, I have shown it to the others who had come with you. Your past."

A shocked Fai whipped his head back, to stare at his companions with a haunted look in his eyes. All of this, however, went by Kamui's mind. The information of Fai's, or rather Yuui's, past shown to him was all that mattered. Kamui knew that this information was what the Dimensional Witch had wanted him to see.

It is not up to me to solve your questions, but know that they will certainly be answered as you set out to find Subaru. That is inevitable.

Those were the Witch's words. Part of the answer should therefore lie in Celes, otherwise the Witch would not have send Kamui to travel with Syaoran's group for only this particular dimension.

The revelation of the mage's past was a past of twins, and Kamui's sorrows were also pertaining his twin. Not only that, Syaoran, too, had a twin of sorts... his clone. Everything involved twins?

Suddenly, Kamui remembered his brother's words, as he was taken away from him by Seishiro.

... and your true twin is also waiting for you.

The Witch had made a similar allusion.

Those who paid your price are closest to you, yet are furthest removed from you...

Kamui had said that there was only one person close to him, that person being Subaru, and had asked who the other one was, but the Witch had evaded that question. What if the other person was his 'true twin'?

The thought made Kamui sick in his stomach. Only Subaru was his twin. No one could replace their bond. Even if Seishiro had cruelly separated them, Subaru and he were still of one blood.

It wasn't until Kurogane had drawn his sword, that Kamui was snapped out of his thoughts to see the current happenings.

Fai attacked. The battle between magician and ninja erupted. Fai attacked Kurogane with his spells, but the ninja was too fast to hit. Evading and then moving forward, he neared Fai like a predator, whilst the magician randomly hit with spells, his eyes and mind too unfocused, too far off in his own past, his own world, to really be a threat to the ninja.

The ninja moved in and slammed Fai's head into the ground. "Your past has nothing to do with me," Kurogane growled. "Besides, if what that guy showed us is your past, then it doesn't make sense, does it? If your magic power is something that grows stronger the more you use it, it'd become more difficult for that 'kill people with magic stronger than your own'-curse to work. However, in the past that I just saw, that guy said: "If this tattoo is traced on your body, further growth of your magic will be restrained until the pattern disappears." Why the hell would you restrain it's growth?"

Kurogane whipped his head to face Ashura-ou. "So, get this farce over with! Showing us a past that would this easily come apart, what the heck are you planning?"

Ashura-ou smiled serenely. "I only want you to grant my wish, Fai."

"I can't do it!" Fai cried out. "You... you saved us from that valley! When you first met us, you treated us with kindness. That's why... I can't kill you!"

Ashura-ou nodded. "Very well..." He made a swishing sound and lifted a body from the waters of the pool behind him. "Shall I continue?" he asked, as Sakura's body floated behind him.

DUN DUN DUN!! Twins have always been something of a mysterious occurrence in the CLAMP universe... What is the secret of the other, the one who is Kamui's 'true twin'...??
