The official website and Twitter account for My Broken Mariko live-action film unveiled a teaser video on May 25, 2022, featuring Mei Nagano as protagonist Shiino, and Nao as Mariko Ikagawa. The franchise also revealed two posters for the upcoming film.

Graphic designer Yori Oshima was in charge of designing the teaser posters. The first poster shows Nagano as Shiino holding the remains of Mariko, and the other shows Shiino jumping off from the veranda of Mariko’s parents’ house.

Yuki Tanada will be the director, and Kosuke Mukai will be in charge of the script with Tanada. The film will be produced by Happinet Phantom Studio and Express and distributed by Kadokawa.

Waka Hirako‘s My Broken Mariko was serialized for four episodes in KADOKAWA’s Comic BRIDGE online from July to December 2019 as Hirako’s first serialization work. It received a lot of attention after its one-volume tankobon was published in January 2020.

The manga won the New Face Award at the 24th Japan Media Arts Festival’s Manga Awards in 2021.

Yen Press published the English edition in November 2020. The publisher explains the story as:

Shiino is an ill-tempered office assistant, but when her friend Mariko dies unexpectedly, she becomes determined to get to the bottom of this mystery. Portraying the soulful connection between girls, this is a striking story of sisterhood and romance.
