Terada, Yoshiyuki

寺田良幸

Yoshiyuki Terada teaches at Tomoeda Elementary School. Throughout the series, as the main characters progress from fourth to fifth grade, he serves as their homeroom teacher. He also instructs other classes, including physical education, and chaperones several school field trips. As the story unfolds, it is revealed that he is in a romantic relationship with his student, Rika Sasaki. In the manga, they become engaged when he gives her a ring, expressing his hope that it will one day serve as her wedding ring. Rika gives him a teddy bear she made and named after herself; legend says this will allow them to remain in love forever. Towards the end of the series, when Sakura is uncertain about her feelings for Li, the couple is shown having a picnic in a park, with Terada slipping away so Sakura does not notice him. During the series, none of the other characters appear to know about the relationship, although when Rika is taken over by the Sword card, Sakura hears her call out "Sensei" (teacher) when she uses the illusion card to show Rika her most beloved.
In the anime adaptation, their relationship is not portrayed in the same light. Their engagement and more romantic scenes are removed, and Rika notes that Terada reminds her of her absentee father. Terada is also shown accepting cakes made by Rika and accepting the bear, naming it after his "hardest working student." In the Cardcaptors English dub, he is simply called Mr. Terada, and all aspects of the romantic relationship between Terada and Rika are completely removed, with Rika's shyness and reactions to him made to appear to be more of a general fear of men than romantic feelings.
