Touya is the king of Clow and the older brother of Sakura. He is very defensive of his sister, though he admits that Syaoran will take care of her. He seems like a tough/cool character, but teases Sakura often.

Despite being royalty, Touya is a proficient fighter with a sword and is highly knowledgeable about the supernatural, most likely due to his close relationship with High Priest Yukito. In theory he has no magical powers, though he might have some intuition about the future.
