Roku Sakura is a Japanese manga artist and writer, primarily known as the creator of the romantic comedy series Busu ni Hanataba o. Sakura is credited as both the author and illustrator of the work, which was serialized in Kadokawa Shoten's seinen manga magazine Young Ace. The series ran for over six years, from its debut on April 4, 2016, until its conclusion on September 2, 2022. Its chapters were subsequently compiled into twelve tankōbon volumes released under Kadokawa's Kadokawa Comics A imprint.

The artist's most prominent work, Busu ni Hanataba o, has served as the foundation for the creator's public profile within the industry. The series received recognition early in its publication run, placing fifth in the print category at the fifth Next Manga Awards in 2019, an accolade that helped solidify its status in the contemporary romance genre. The work's premise focuses on a self-deprecating high school girl, Hana Tabata, and her interactions with her popular classmate, exploring themes of self-esteem and social hierarchy. The series' development is noted to have originated from a plot prototype shared on the Pixiv platform in 2015, with the final work incorporating elements inspired by classic shōjo manga and otaku culture, including character names derived from Yamanote train stations.

The significance of Roku Sakura's work expanded with the announcement of an anime adaptation in November 2022, which was revealed concurrently with the release of the twelfth and final manga volume. This adaptation is being produced by the animation studio SILVER LINK., with a premiere scheduled for July 2025. In anticipation of the anime's release, a special edition series titled Busu ni Hanataba o. ~Bloom~ was announced to begin serialization in Young Ace in 2025. The manga has also been licensed for English-language publication by Yen Press, with the first volume released in November 2024, further extending the creator's reach to an international audience.
