Oikura, Sodachi

老倉育

Araragi's childhood friend. She is a student with a strong sense of competitiveness, which earned her a popular nickname much to her chagrin.
Sodachi was the president of a first-year class that included both Hitagi and Koyomi. At school, she wanted to be called "Euler," but ended up getting the nickname "How Much," a pun on her surname (お幾ら, o-ikura) and a reference to her personality.
