It was serialized on Shueisha's Shōnen Jump+ manga service from November 2020 to December 2023. The manga is based on the legend of Kuchisake-onna, a monstrous woman in Japanese folklore said to have scars on the sides of her mouth. It is Kajimoto's third romance manga based on Kuchisake-onna; she had previously released the one-shot Her Special Seat in 2017, and three-issue series Even If You Avoid the Slit in 2018. The latter shares the same Japanese name as Even If You Slit My Mouth and features alternate versions of the same characters.

Miroku, a notorious yōkai known for her slit mouth, has felt her powers wear down in recent years as the public's belief in the supernatural has declined. To save herself, she must submit to an arranged marriage with Koichi Sano, the son of a human family charged with aiding supernatural beings. Miroku strikes a deal with Koichi to call off the engagement if she is able to scare him before his eighteenth birthday, but she must go through with the wedding if she falls in love with him.
