Yoshiyuki Terada (寺田 良幸, Terada Yoshiyuki) is a fictional character in CLAMP's anime and manga series Cardcaptor Sakura. Terada-sensei, as he is addressed by all of his students, is a teacher at Tomoeda Elementary School. Through the fourth grade and part of the fifth-grade year, he is the homeroom teacher of Sakura Kinomoto (Sakura Avalon in Cardcaptors) and every other recurring elementary student character. Terada appears to teach a variety of subjects, including physical education, where he is seen in a gray sweat-suit and equipped with a whistle.
Terada is not directly involved in any Clow Card plot, although he is generally always nearby as a chaperon on school field trips and events (where Clow Cards frequently appear). Because he has no magical ability, Terada never realizes most of what is happening or instead just considers it peculiar (i.e. unusual weather conditions).
While he appears to be simply a filler character in the series, Terada does play a role in the manga for his relationship with student Rika Sasaki.
Relationship with Rika Sasaki
In the manga, Terada is Rika's fiancé and elementary school teacher. They supposedly became engaged near the beginning of the series when Terada presents Rika with a ring, explaining that he hopes one day it will become a wedding ring. This suggests that they have been spending time with each other prior to the start of the manga, where Terada may have also been Rika's third grade teacher. Throughout the entire series, Terada and Rika have continued to exchange moments and soft, blushing glances whenever possible. Their relationship remains unannounced in canon, and their few interactions appear to go completely unnoticed except for two students, Sakura and Tomoyo. Tomoyo is able to observe and respect the secret bond they share, but Sakura remains oblivious and confused whenever she notices Rika or Terada blushing.
In the anime, Terada and Rika are not engaged, but Rika maintains her schoolgirl crush on Terada-sensei. Rika states that Terada reminds her of her absent businessman father. Terada always accepts the cakes she bakes for him, as well as appreciating the teddy bear that she gives him in episode 50. He decides to name it after her, saying that he considers his hardest working student.
The references to the relationship are eliminated entirely, as Rika's shyness toward Mr. Terada is presented in a way that implies that she is afraid of him.
