Saikyou Degarashi Ouji no An'yaku Teii Arasoi ~Teii ni Kyoumi Nai desu ga, Shinu no wa Iyana no de Otouto wo Koutei ni Shiyou to Omoimasu~

Saikyou Degarashi Ouji no An'yaku Teii Arasoi originated as a web novel series written by Tanba, which gained significant traction on the user-generated publishing platform Shosetsuka ni Naro. The narrative follows Prince Arnold Levis Haupt, a protagonist who feigns incompetence to avoid the dangers of a cutthroat imperial succession struggle, while secretly orchestrating events to ensure his younger brother ascends to the throne. Its success in the web space eventually led to a light novel adaptation published by Kodansha under their Ranobe Bunko imprint.

The light novel series features illustrations by Yuunagi, whose clean and expressive character designs helped solidify the series' aesthetic. The work is representative of the 'hidden genius' subgenre of Japanese light novels, where the appeal lies in the contrast between the protagonist's public perception as a good-for-nothing prince and his actual tactical brilliance. Upon its release, the series was well-received by fans of political intrigue and fantasy, leading to further adaptations including a manga version illustrated by Arata Aki.
