Koyomi’s underclassman, star of the school’s basketball team and one of Hitagi’s acquaintances from back in junior high school. She is so well known in her school that not a single student had not heard of her, mostly because it was her who was responsible of the rapid rise of success of the school’s girls basketball team due to her talents. She considers herself a lesbian, fujoshi, lolicon and masochist. Her hobbies include reading yaoi literature and playing basketball. Although her sexual preference is clearly towards females, she does not have a hard time interacting with males, and she even manages to say teasing remarks when she is comfortable with the person she talks to (i.e. Araragi). She is 160cm tall.
Suruga is a girl with brown eyes and dark bluish hair. Because of her club activities as a basketball varsity player, she boasts an athletic physique, although she admits that her breasts might not be ample enough for Araragi to notice.
