Nio Nakatani began developing the series to contrast with her previous manga God Bless the Mistaken, with that series featuring a more gentle world, as opposed to Kimi wa Shūmatsu more chaotic one. The idea was inspired by Makoto Shinkai's film Weathering with You, with Nakatani wanting to create a boy-meets-girl story where the girl could cause consequences, such as the end of the world. Although the final manga ended up being a romantic story, she originally planned it to be a more action-focused series; however, she abandoned the idea as she felt that the concept did not work out. Yutaka and Aru's relationship was originally intended to be more friendly rather than romantic, with her editor suggesting the change to the focus on romance.

The series is written and illustrated by Nio Nakatani, who previously serialized the manga Bloom Into You in ASCII Media Works's Dengeki Daioh magazine from 2015 to 2019. It began serialization in Dengeki Daioh on September 27, 2025. The first tankōbon volume was released on February 27, 2026; two volumes have been released as of August 27, 2026.
