Oikura Sodachi

Японское имя:	老倉 育
Прозвище:	How Much

Sodachi, the main character of Sodachi Riddle and Sodachi Lost, is a girl with twin-tails and was the class president of a first-year class where both Hitagi and Koyomi also belonged to. She loves mathematics and deemed it as beautiful. She despises Koyomi for an unknown reason but Koyomi thinks that it's because he is better at math than her. At school, she wanted to be called as "Euler", but ends up getting the nickname "How Much", a pun on her surname (お幾ら, o-ikura) and a reference to her personality.
