A New World is the 1st chapter of Tsubasa World Chronicle: Nirai Kanai-hen.
Syaoran had contacted Watanuki to retrieve some items that were unavailable in his world, that he needed for his quest. To achieve this task, Watanuki had travelled to a world where both the shop and Yuko existed.
The story opens with Syaoran and Watanuki communicating via Mokona, and it picks off exactly from xxxHolic Rei's chapter 38. As the chapter begins, Watanuki reflects on Syaoran's adressing of him, calling him Kimihiro, and him being the only one who calls him by his name instead of his last name (except for Kohane, who was missing in the entire Rei series). And this is because of the deep bond they share.
For him to live in a world with Yuko and the shop would have created a paradox (since he is now the "Owner" of the shop), so he needed to be "his old self", by forgetting his memories and taking Doumeki and Himawari's memories with him.
Syaoran realizes that this request had given Watanuki pain, since he had gone back to past days where he lived happily with Yuko in her shop. But eventually he remembered everything, though Syaoran wonders if he wanted to stay with her, Watanuki replies that she wasn't the "real Yuko". Syaoran apologizes for having Watanuki go through the pain of parting from Yuko again, but Watanuki replies that going there was his decision and Yuko herself had told him, that as we choose, we move on, to forge the path of our own destiny.
He then proceeds to transfer the items listed above to Syaoran. Watanuki confirms that in his world, where Yuko no longer exists, he will continue to wait for her. Syaoran reminds him that there are people who are worrying and waiting for him, including himself of course.
Mokona then reflects on how going through the pain of separating from Yuko must have been hard for Watanuki to bear and thus, Syaoran declares that they must make the best of the items given by him.
Kurogane and Fai enter the room afterwards. After hearing news of Watanuki, Fai feels sorry for him. Syaoran sees him and looks sad as well.
To try and lighten things up, Kurogane tries to get them to drink sake. Fai gets some fruits, while they comment that it's all good in Nirai Kanai (the current world they're at). They say that fish is good, the climate is good (not too warm), and the sea is nice. Then Kurogane bursts into the conversation saying that they must stay until the person they're looking for shows up. Syaoran comments that his arm is broken, and that they must also wait for it to be repaired. It seems that the person who will bring his new arm is Seishirou and not Fuma, as it happened in Tsubasa Reservoir Chronicle. Then Fai reflects on how similar both brothers are, since both their intentions deep down are the same [both looking for something they've lost].
Masayoshi (originally from Clamp School Detectives) appears and greets the group. He reflects on how peaceful things are, in this world, because of the Godess. He offers them some food, while reminding them that once people started praying to her, they've been blessed with the good climate and no floods since. He also invites them to the festival in her honor that night.
Later on, that night, they attend to the Festival, to find tons of people releasing paper lamps into the air, and they find the Goddess and her bodyguards who turn up to be Hana, with Sakura and Tachibana (originally from Gate 7). She states that she's been waiting for Syaoran.
