Sodachi is Araragi's childhood friend and a fellow first-year student. She's got a competitive streak that's basically her defining trait—so much so that she earned a nickname she absolutely hates. The name "How Much" is a pun on her surname and reflects how driven she is, though she'd much rather go by "Euler." She ended up as class president during her first year, alongside Hitagi and Koyomi.
