We learned about a new anime adaptation in the works in July 2021 with Kadokawa confirming that Mamahaha no Tsurego ga Moto Kano Datta aka My Stepmother’s Daughter Was My Ex-Girlfriend, had gotten the green light.
The series has Shinsuke Yanagi directing it based on the scripts written and overseen by Deko Akao.
A manga adaptation began in 2019 by Rei Kusakabe with three volumes out so far.
