Rennyuu Order The Animation

This reverse-isekai story begins when Sasha, the stunning princess of the mystical desert kingdom Al Fajar, suddenly appears before Takayuki—a young man living alone in Japan while his parents are away on archaeological excavations.

Sasha carries an official letter from Takayuki’s father declaring that she has officially become his wife. While Takayuki is still reeling from total shock and confusion, Sasha takes full initiative, demanding he fulfill his marital duties to provide her with a royal heir as quickly as possible. With her sun-kissed skin and voluptuous, inviting figure, the exotic princess transforms Takayuki’s quiet everyday life into endless nights of overwhelming sweetness and passion.
