Okita launched the manga in December 2013 in Kodansha’s Kiss Plus magazine, where it ran until the magazine ceased publication in February 2014.
The manga centers on nursing student Bakka who begins her residency at an obstetrics and gynecology clinic on her mother’s recommendation.
The March issue of Kodansha’s Hatsu Kiss magazine revealed on Tuesday that Bakka Okita’s Tōmei na Yurikago (The Invisible Cradle) manga will have an important announcement in the magazine’s next issue on April 13.
It continued in Kiss Plus’ successor magazine Hatsu Kiss in June of that year.
