Tsubasa: RESERVoir CHRoNiCLE

The statues of Ashura and Yasha continue to glow as the sky appears to crack, so Mokona transports Sakura and Syaoran to a different world, where they meet Ashura who appears to be in a war with Yasha. Sakura and Syaoran discover Fay and Kurogane (with black eyes), but are they the companions they have had all along?
