Square Enix's Gangan Joker revealed today that manga will end in the magazine's next issue on June 22nd. The manga will be featured on the magazine's cover and will have a color splash page. The manga's 9th and 10th volumes will be released simultaneously on July 22nd.
Yen Press has licensed the manga and describes the story as:
Satou Matsuzaka doesn't seem to care much about it, fussing over boys and tossing them aside like used candy wrappers. But all that changes when she meets Shio. The girl changes everything for Matsuzaka. Is this love…? If so, then it's love through a very distorted prism, as the high school student demonstrates that there's no atrocity beyond her reach when it comes to protecting the object of her mad affection.
Kagisora launched the manga in Gangan Joker in 2015, and Square Enix published the manga's eighth compiled book in June 2018. Yen Press released the manga's first volume on Tuesday. The manga inspired a television anime adaptation by Studio Ezo'la and directed by Nobuyoshi Nagayama (My Girlfriend is Shobitch) that premiered in July 2018. Amazon Prime Video streamed the anime in Japan.
Other Kagisora series include the manga adaptation of the anime Tari Tari, Kamiyome and Fantasista Doll ~Prelude Kagami~.
