Yoriko Matsumoto

Yoriko Matsumoto serves a dual role in Yuyushiki as both an English teacher and the supervising advisor of the Information Processing Club. Her nurturing and easygoing nature has earned her the affectionate nickname 'Mom' among her students. While she often struggles to keep up with the trio's offbeat conversations and unpredictable banter, she remains a steadfast and caring presence for the club. Her endearing absent-mindedness occasionally shines through, most notably when she quietly brought the club's computer home for personal use.
