Hana appears to fight the being, revealing herself to be a , a woman tasked with defeating evil spirits known as . After the attack, he wakes up at the Night District Castle, where he learns that he is now tasked with recruiting and taking care of the Hanamiko.
Ryà Âma Kitada originally developed the idea for the series while working on his previous series Yumeochi: Dreaming of Falling for You. He originally pitched a draft version to Shueisha, which declined the proposal. With their permission, he decided to pitch it to Kodansha instead, which agreed to serialize it. He originally envisioned a fantasy series set in a city inspired by the Edo period, but decided to switch to a modern-day setting as he felt the premise had become too fantastical.
The series was originally intended to have a female protagonist, but Kitada changed it to have a male protagonist to make it more relatable to readers. He cited works such as Spirited Away and other Studio Ghibli films as inspirations. Due to his lack of experience writing a Japanese-style fantasy, he did research on the Edo period, including red-light districts of the time and the language used there. He made sure to include archaic language to fit the series' themes. To make the series more distinctive, he decided to include kanji onomatopoeia.
The series is written and illustrated by Ryà Âma Kitada, who had previously serialized the manga series Super HxEros in Shueisha's Jump Square magazine, and Yumeochi: Dreaming of Falling for You in Shueisha's online service Shà Ânen Jump+. It began serialization in Kodansha's Magazine Pocket service on July 22, 2024. The first tankà Âbon volume was released on October 8, 2024, with a Kodansha representative stating that a reprint was decided on a week after release.
