Tsubasa Chronicle episode 2

In ep2, Syaoran brings Sakura to meet this dimension witch(i think thats her name). He is joined by Fye (he came on his own will to escape the king of his world), and Kurogane (who was sent here by the queen of his world, Tomoyo, unwillingly). Fye doesn't wanna go back, Kurogane wants to go back and Syaoran wants to go to other worlds to get back Sakura's wings. So, in exchange for their wishes, they have to sacrifice sth that is most precious to them. For Syaoran, it would be his relationship with Sakura. The first world they arrive at is in the midst of a gang war. They use kudans to fight. And when in danger, Syaoran's own kudan, which is top level, appears to save him. Intrigued/annoyed, the two gangs are eager to fight him.
