Summary
Sodachi Oikura is Araragi's childhood friend and a student defined by her intense competitiveness, a trait that ironically earned her a popular nickname she deeply resents. During their first year, she served as the class president alongside both Hitagi and Koyomi. While she preferred to be addressed as "Euler" at school, her peers instead dubbed her "How Much." This moniker is a pun on her surname, Oikura, which sounds like the Japanese phrase for "how much," and serves as a direct reference to her calculating personality.
