The official Twitter account for Idea Factory and Otomate's Collar X Malice franchise revealed on Sunday that the game is inspiring an anime adaptation, as well as a second stage play next spring. The announcement, first made at Otomate Party 2019 event earlier in the day, did not reveal the format of the anime.

Otomate released the original otome mystery visual novel in Japan in August 2016, and Aksys Games released the game in English in July 2017. Aksys Games describes the story:

A dangerous shadow organization launches a campaign of fear and violence in the city of Shinjuku, pushing society to the brink of chaos. As a young police officer tasked with restoring order, you become the target of an attack, and have a poisonous collar attached to your neck. With the situation spiraling out of control and time running out, five mysterious strangers appear to aid you in your quest for the truth. Who can you trust? Will you be able to save yourself and the soul of Shinjuku from the clutches of oblivion?

The Collar X Malice Unlimited fan disc — which included an interlude, sequel story, and three side stories — shipped for PlayStation Vita in Japan in July 2018. Both the original game and Collar X Malice Unlimited will appear on the Switch, with the original game slated for the Switch in 2020.

The franchise's first stage play ran at Tokyo's Theater Sun Mall from May 2-12, 2019, and then in Osaka's Matsushita IMP Hall from May 17-19.
