Touya Kinomoto is the older brother of Sakura. He is a 10th grader (Sophomore year) in Seijou High who is also the classmate of Yukito. You can tell that he is the kind of brother who always pisses you off and at the same time hides deep inside that he really, really cares for you and is so over protective..

He always calls Sakura "Kaijuu!" or greets her with "Osuyo…" [*vocabulary] He shows that he doesn’t care for Sakura. But when he feels that Sakura is in trouble, he comes in saving her.

Touya also has powers of his own. That’s why in episode 65, he gave all his powers to Yue but then making him promise that he will save Sakura in any trouble because he won’t be able to feel it Sakura is in trouble anymore.

He was also very suspicious of Kero. That’s why when ever he wakes up Sakura, before leaving, he still stares at Kero which always makes Kero sweat drop.

[*Vocabulary]
Kaijuu - monster
Osuyo - good lateness (at least that’s what’s in the subtitles…)
