The My Stepmom’s Daughter is My Ex anime revealed a new trailer earlier this month, and now we’re turning our attention toward a couple key cast members. Following up on the previous cast reveals, the official accounts announced who will be voicing the stepmom and dad in the series.
Kazuyuki Okitsu (Jonathan Joestar in JoJo’s Bizarre Adventure) will be voicing Mineaki Irido:
Ai Kayano (Mamako Oosuki in Do You Love Your Mom and Her Two-Hit Multi-Target Attacks?) will be voicing Yuni Irido:
As for the previously announced cast, Rina Hidaka plays Yume Irido, Hiro Shimono plays Mizuto Irido, Ikumi Hasegawa plays Akatsuki Minami, Nobuhiko Okamoto plays Kogure Kawanami, and Miyu Tomita plays Isana Higashira.
The anime is being made at project No.9, with Shinsuke Yanagi of Bottom-tier Character Tomozaki working as the director. Scripts are being both overseen and written by Deko Akao, who has also worked on Komi Can’t Communicate. The music is being composed by Hiromi Mizutani, who previously did music for Hell Girl and Non Non Biyori.
J-Novel Club publishes the original light novels in English, and gave this description of the series:
“Ah, high school. Is there any better place to start fresh after a horrible middle school relationship? Nope! Not unless your ex ends up at the same school as you and is now your stepsibling. What was supposed to be a sanctuary of peace where I could avoid ever seeing her again has become a living nightmare! Everywhere I look, I see her—in my house, in my school, in my class. There’s no escape! She even claims that she’s the older sibling. Like hell she is!
But I won’t lose to her. After all, I’m the older brother in this new family situation. That’s right, we’re family now. No matter how much we may have thought we loved each other before, we saw one another’s true colors and realized we weren’t meant for each other. That’s why even though we may keep up a buddy-buddy sibling act for the sake of our parents, things will never go back to the way they used to be.”
