Tensei Shitara 15-sai no Ouhi deshita: Moto Shachiku no Watashi ga, Toshishita no Kokuou-heika ni Semararete Imasu!?

This light novel series, authored by Ononata Manimani, emerged during the mid-2010s amidst the significant rise in popularity of the 'isekai' subgenre within Japanese web-novel culture. It was originally serialized on the user-submitted platform Shosetsuka ni Naro before being picked up for print publication by SB Creative under their GA Novels imprint. The narrative centers on a protagonist reincarnated into a 15-year-old queen, exploring themes of corporate burnout from her previous life set against the backdrop of a sudden royal courtship.

The character design and illustrations for the print release were handled by various artists throughout the series' run, following the typical industry practice of pairing light novel authors with specialized illustrators to establish a distinct aesthetic for the physical editions. The series is received by readers as a lighthearted romantic fantasy, contributing to a broader trend of Japanese literature that reimagines the professional anxieties of the modern workforce through the lens of noble fantasy scenarios.
