Haruomi Tomotsuka is a Japanese manga artist recognized as the creator of the supernatural comedy series Dara-san of Reiwa. Tomotsuka first began developing this work as a webcomic, initially sharing it on a personal Twitter account in October 2021. The positive reception to this early online release led to a full serialization deal, and the manga officially launched on Kadokawa's ComicWalker (later rebranded as Kadocomi) and Nico Nico Seiga websites on March 30, 2022. The series is published in print by Media Factory under their MF Comics imprint, with six collected tankōbon volumes released as of mid-2025 and a seventh scheduled for December of that year.

Tomotsuka's most notable original work remains Dara-san of Reiwa, which has achieved significant commercial and critical recognition. The series was a nominee for the eighth Next Manga Awards in the web category and secured a place in the top twenty of the male readers' category in the 2024 edition of the influential Kono Manga ga Sugoi! guidebook. The property has also expanded into a voice comic, featuring the talents of voice actress Fairouz Ai as the titular character. Demonstrating the project's growing industry significance, a television anime adaptation produced by studio Asahi Production was announced for a 2026 premiere, with Masato Suzuki serving as director and Koichi Kikuta handling character design.

The artistic identity of Haruomi Tomotsuka, as evidenced by this primary work, centers on blending horror elements with slice-of-life comedy. The official English synopsis from Yen Press highlights this juxtaposition, describing a narrative where two young siblings encounter a terrifying, grotesque deity of misfortune who immediately questions why they are not frightened of her. This premise establishes a recurring theme of mundane, often heartwarming interactions with supernatural beings typically associated with fear and calamity. The series is specifically categorized as a horror comedy aimed at a seinen demographic, and its chapters have been collected and published in English by Yen Press. The creator's path from a self-published webcomic on social media to a serialized manga with a confirmed anime adaptation also represents a modern success story within the contemporary manga industry.
