Hinako Seta is a Japanese manga artist and illustrator known primarily for creating the four-panel manga series Re-Kan!. She made her professional debut in 2005 as an illustrator for light novels published under the Kadokawa Beans Bunko imprint. Her early career included illustration work for several light novel series, including The Legend of Zangetsu, The Legend of the Star Princess, and the Spiral Princess series. She also contributed manga adaptations and short works based on existing properties, including a four-panel manga set in the Keroro Gunso universe and an adaptation of The Young Kindaichi's Casebook.

Seta is best known as the original creator of Re-Kan!, a comedy and supernatural four-panel manga. The series was first published as a one-shot in Houbunsha's Manga Time Jumbo magazine in December 2009, and it began regular serialization in the same magazine starting with the February 2010 issue. The manga later moved to Houbunsha's Manga Time magazine in April 2018 when Manga Time Jumbo was discontinued. The serialization concluded on August 7, 2025. The series was collected into multiple tankobon volumes. In 2015, Re-Kan! received a thirteen-episode anime television adaptation produced by the studio Pierrot+, which aired in Japan from April to June of that year.

Beyond Re-Kan!, Seta has created numerous other four-panel manga series. Her other works include Connect! Black Phone-chan, published in Houbunsha's Manga Time Family magazine, as well as Pretend Play Girl and the Artificial Human and The Unpopular Girl Living with a Hero, both serialized in Futabasha's Manga Town. She has also created series such as Kokonose no Kanata and Ashinoya's Cat. As of 2015, she resided in Saitama Prefecture, and she has stated that she created her manga using a combination of traditional paper-and-pen methods and digital computer finishing. Her work focuses primarily on the four-panel comic strip format, and Re-Kan! remains her most prominent and widely recognized creation due to its anime adaptation.
