The Demon King and the Witch is the 226th chapter of Tsubasa: Reservoir Chronicles.
Syaoran looks shocked as he finally realized what happened. Mokona is happy that the clones are back, while Kurogane protests that Fai already knew and he didn't say anything.
Fai replies that if he had been wrong Kurogane wouldn't have stopped beating him, as well as the clones for their disappearance. The clones are taken aback by Kurogane's words of affection and smile, while he adds to Syaoran that the same goes for him and his princess. He nods in reply.
Syaoran exchanges glances with his parents, surprised, while they both smile at him. The clone strokes his hair while telling him, regardless of him being his child or his original self, he is a most precious person to him. He tries to reply, though Fei Wang, looking desperate, casts a spell on them causing the area to crumble and break apart. Mokona shouts at them that "everything is frozen" meaning the dimensions and the flow of time have stopped. Fei Wang's mark appears while he whispers that the Witch of Dimensions is gone from every world.
He looks disturbed as he continues to whisper and wonders to himself, is she really dead? Then he inmediately shouts, he will indeed revive her.
