Robinson Haruhara is a Japanese manga artist and original creator, born on March 12, 1986. He is male and began his professional career after working as a production assistant at an animation studio, a position he left due to health and stress-related reasons to become a freelance manga artist. He first gained recognition for his MAD anime videos on the streaming platform NICONICO动画. His professional debut came when he was invited by Dwango, the parent company of NICONICO, to serialize his first major work on the newly established NICONICO漫画 platform.

Haruhara is best known as the creator of the fantasy comedy series Senyū. (also known as Battle Spirits), which began serialization on NICONICO漫画 in August 2010. The series proved popular and was adapted into two seasons of a short-form anime television series in 2013, collectively totaling 26 episodes. Senyū. has a complex publication history, existing in multiple versions. The original web comic ran in several chapters, and a separate, parallel storyline with similar characters but different plots was serialized in the print magazine Jump Square. A more faithful print adaptation of the original web comic, titled Senyū. Main Quest, was later published by Kodansha. Haruhara has continued the universe with a long-running short story collection, Senyū+, and a subsequent series, Senyū F5.

Another of his notable works is Gakumon! ~Ōkami Shōjo wa Kujikenai~, which he authored and illustrated. The series was serialized in Jump Square from 2014 to 2016. It received a flash anime adaptation, which is one of the credits mentioned in the query.

Haruhara is also the original story writer for the popular manga 'Tis Time for "Torture," Princess (Hime-sama "Gōmon" no Jikan desu). This series began serialization on Shueisha's Shōnen Jump+ website in April 2019, with artwork provided by illustrator Hirakei. The series has been collected into multiple tankōbon volumes and has been licensed for English release by Manga Plus. An anime television series adaptation produced by Pine Jam aired from January to March 2024, and a second season is scheduled to premiere in 2026.

Haruhara has worked on numerous other titles, often serving as the original creator or writer. These include the action comedy Hero Hearts, the supernatural series Angel Game (with artist Machida Toshiko), the fantasy comedy Sugiyami Enforcement Agent ~People Working in Another World~, and the slice-of-life series Saeki-san wa Nemutteru. He has a distinct artistic identity, often favoring comedic fantasy settings. He has openly stated that he avoids creating overly detailed character profiles for his works, preferring to let his characters feel as though they exist naturally. He is also known to be supportive of fan works based on his creations.
