Mr. Terada

Yoshiyuki Terada is Sakura's teacher and homeroom teacher. He is very caring of his students and would try to do anything to keep them out of harms way.

When Rika was hypnotized by "Sword", Sakura used "Illusion" to show the person that Rika cared the most for, Yoshiyuki Terada.

Anyways, in the manga, after Rika graduated from high school, Yoshiyuki Terada and Rika supposedly got married. Athough it wasn't actually shown, it was made clear that it was going to happen as Terada gave Rika a ring. In the anime, though, it seems as if we only see Rika's point of view. Whenever Rika seemingly makes goo-goo eyes at Yoshiyuki Terada, he becomes flustered and can't understand what's going on.

Overall, Yoshiyuki is very kind, and caring.
