My Stepmom's Daughter Is My Ex

Aired: 2022

A TV anime produced by project No.9, based on the light novel series by Kyosuke Kamishiro, published by KADOKAWA under the Kadokawa Sneaker Bunko imprint, with illustrations by TakayaKi. Originally from "Kakuyomu," the work won the Grand Prize in the Romantic Comedy category of the 3rd Kakuyomu Web Novel Contest. The series has exceeded 1.3 million copies in circulation (as of October 2024). Mizuto Irido and Yume Ayai became a couple in middle school but broke up over trivial disagreements at graduation. However, just before high school, their parents' remarriage reunites them as step-siblings. "Obviously I'm the older brother" vs. "Obviously I'm the older sister"—neither will yield as they live under the same roof as ex-lovers. 12 episodes. Main cast includes Hiro Shimono as Mizuto, Rina Hidaka as Yume, and Ikumi Hasegawa as Akatsuki. Music by Hiromi Mizutani. ©Kyosuke Kamishiro, KADOKAWA / TsureKano Production Committee
