Crossover of Tsubasa Chronicles and Carcaptor Sakura

Author's POV:

This chapter may feel you dizzy because we have two worlds. The first world is in Tsubasa Chronicles and the second world is held in Cardcaptor Sakura.
But we also have dimensional witch's place in XXX Holic but it is not placed in the two worlds. It is the dimension of the two worlds.

2nd world:

Syaoran came back from Hongkong and she first met Sakura. They planned that they will have a private date without letting it know to Tomoyo. The next day, they are so excited to have it. Syaoran prepared to go with Sakura but before leaving, he brought his weapon. Same through with Sakura, she brought her Sakura cards. They had all their fun in the amusement park.

"Can we go to a quiet place without people?" sakura said.
"sure. Whatever you want." said the blushing Syaoran.

They sat down on the bench and they are tired. (They also don't know that they are being followed by Tomoyo, Kero and Yue)

"Can I take a nap?" Sakura said.
"Go on. I will guard you until you wake up." said Syaoran.

Sakura fell asleep and Syaoran was sightseeing. And when Syaoran have hold her hand, they was a bright light making Syaoran disappear.

1st world:

Syaoran and Sakura was tired from a long journey. Fai and Kurogane have returned from their worlds. Sakura went to her own bed and slept soundly. Syaoran was guarding her and when he hold her hand, there was a bright light too, making himself disappear.

Dimensional Witch's Place:

Clow was there meeting with Yuuko together with Watanuki holding Mokona in his hand.

"I want my wish to be granted." said the serious looking Clow.
Yuuko said, "What is your wish? It requires compensation."
"My wish is to .

.
switch the Syaoran in the first and second world for a week."
"Your wish is already granted and paid." said Yuuko.

Then Clow has already left to somewhere else.

Watanuki said, "Yuuko-san, what did he pay to you?"
"He paid me a strong barrier and this." said Yuuko.
"What is that? They look like Mokona."
"This is a greatest power that I received" said Yuuko.
