Kodoani.com – Official Twitter account for anime My Stepmom’s Daughter Is My Ex (Mamahaha no Tsurego ga Moto Kano Datta) revealed on Thursday its first teaser promotional video, key visuals, voice cast, staff, and 2022 premiere.
The voice cast includes Rina Hidaka as Yume Irido and Hiro Shimono as Mizuto Irido.

J-Novel Club licensed the light novel series and it describes the story:
Ah, high school. Is there a better place to start over after a horrible high school relationship? No! Not unless your ex went to the same school as you and is now your step-sibling. What was supposed to be a sanctuary of peace where I could avoid seeing her again has turned into a living nightmare! Everywhere I look I see her — in my house, in my school, in my classroom. No way out! She even claimed that she and I are sisters.
But I won’t lose to her. After all, I am the older brother in this new family situation. That’s right, we’re a family now. No matter how much we might have thought we were in love before, we’ve seen each other’s true colors and realized that we’re not meant for each other. That’s why even though we can keep a sibling act of best friend for the sake of our parents, things will never go back to the way they were.
