* '''[[Syaoran Li#Syaoran in Tsubasa|Syaoran]]''':
The hero of the story. A crossover character from ''[[Cardcaptor Sakura]]''. He ( at this point) does not have any magical power, but is an excellent martial artist and an aspiring archaeologist with extensive knowledge of various languages, histories, and artifacts. His right eye is blind; sometimes, in mysterious dreams, he can see out of the eye and look at a person he does recognize as himself in endless mirrors. Syaoran was found in his childhood wandering the streets without a memory, before he was discovered and adopted by the man he now calls father (Sakura's father in Card Captor Sakura), who recently passed away, leaving his foster son to continue his great work. He obtained his sword Hien during his stay at Ōto, which he learned to use from [[Kurogane]], and learned his fighting abilities from now- enemy Seishirō, who can also travel between worlds and says he is looking for vampires.
* '''[[Sakura Kinomoto#Tsubasa Chronicle|Sakura]]''': The Princess of Clow Country. Sakura is a cheerful, selfless, and stronghearted being. She states if there was ever something that she could do, she would try her absolute best. She possesses a mysterious power, namely her "wings" that can actually change the world, though it will still be a while before anyone understands what that means. Her wings are the manifestation of her soul, namely her heart and memories. She is targeted by Fei Wong for that very power. After losing her memories, Syaoran gave up their relationship in order to save her. Meaning, even if she regains all of her memories, the one that she would never retrieve would be the knowledge of Syaoran's existence. Her main goal is to get back all of her memories and return home. A crossover character from ''[[Cardcaptor Sakura]]''.
* '''[[Kurogane]]''': A rough-mannered ninja from the world of Nihon ('''[[Japan]]'''), exiled for his recklessness.

He obtained a new sword in Ōto called the Sōhi, and taught Syaoran the skills of sword fighting and sensing attacks from the right. Kurogane is an original character and is not from any other Clamp work.
