A manga adaptation with art by Yumika Kanade is currently running in Shonen Ace Plus, with three volumes released. Yen Press, who publishes the light novel and manga in English, describes the series:
Yuuta Asamura is still figuring out how to interact with his new stepsister, Saki Ayase. After discovering they have more in common than expected, the two reach a comfortable equilibrium, but things start to get out of whack when Saki fails one of her exams and asks for Yuuta’s help. Then Yuuta’s attractive college-age coworker, Shiori, invites him out on a date, and Saki finds a strange new emotion welling up in her heart…Just what is this feeling?
