Square Enix's Gangan Joker revealed today that manga will end in the magazine's next issue on June 22. The manga will be on the cover of the magazine and will have a colorful home page. The 9th and 10th volumes of the manga will be released simultaneously on July 22nd.
Yen Press licensed the manga and describes the story as:
Satou Matsuzaka doesn't seem to care much about this, messing with the boys and leaving them aside as if they were well-used candy wrappers. But all that changes when she meets Shio. The girl changes everything for Matsuzaka. Is this love…? If it is, then it's love through a very distorted prism, as the high school student demonstrates that there is no atrocity beyond her 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), which premiered in July 2018. Amazon Prime Video broadcast the anime in Japan.
Kagisora's other series include the manga adaptation of the anime Tari Tari, Kamiyome, and Fantasista Doll ~Prelude Kagami~.
