Your pet? Sayuki Tokihara

Sayuki Tokihara is one of the main characters of the Hensuki series. She is a third year student and the calligraphy club's president. Sayuki has long, flowing blackish-gray hair with bangs, adorned with a red headband that has a ribbon bow on the side. Her eyes are large and golden-yellow, giving her an expressive look. She is wearing a pink blazer with a white shirt underneath and a red bow tie at the collar, typical of a school uniform. Her skirt is a blue and purple plaid pattern, pleated and short, adding to the classic schoolgirl aesthetic. She also has thigh-high dark stockings that complement her outfit, paired with brown loafers. On the outside, Sayuki is a mature upperclassman who has a playful attitude and a kind spirit. She enjoys calligraphy and tends to make a huge mess whenever she is writing. She always seems to be at odds with Yuika Koga and teases/picks on her, the same goes both ways. However deep down, Sayuki is actually a huge masochistic pervert who has a fetish for being dominated and wants Keiki Kiryuu to make her his pet. She proclaimed that she was envious of a dog and owner whom she interacted with as she wants to have that master-pet relationship with Keiki. It is shown that Sayuki actually does not enjoy doing calligraphy, but enjoys the company of others in the club. This is why she is protective of it and was desperate in finding a new member after her upperclassmen left. However, she almost dropped her intention of protecting the club when Yuika pointed out that Keiki—who was temporarily a member of the student council to prevent the club from disbanding—had every right to join the student council as a full-fledged member. This implies that Sayuki wants to protect the club where she can spend time with Keiki.
