Written and illustrated by Masaoki Shindo [ja], RuriDragon was initially a one-shot published in Shueisha's Jump Giga magazine on December 28, 2020.

[2][6] On August 1, 2022, Weekly Shōnen Jump announced that the series would go on indefinite hiatus due to Shindo's health.

[16] In July 2022, a set of digital stickers based on the series was released in the instant messaging service Line.

[25] The first chapter received positive reviews from Japanese readers, who found the art "cute" and said that the story's loose atmosphere is not typical of a Jump manga.

[26] Brian Salvatore of Multiversity Comics praised the art and tone for approaching the juxtaposition between Ruri and her surroundings in a way that balances comedy and absurdity, adding that the way the story unfolds "seems natural to 'real' life".

[28] Writing for GamesRadar+, Austin Wood praised the manga for its "clean art and stellar expressions" and how it approaches its fantasy premise, adding that its setting, pacing, and main character are a stand out within Shōnen Jump's lineup.
