False Princess Iruruu

You play as Iruruu—a girl from a remote tribe in the Western steppes of imperial China. She's suddenly called upon by the Celestial Court to become a royal consort in the rear palace. Although reluctant to leave behind her quiet and peaceful life in the steppes, she embarks on this mission knowing it will bring great political influence to her tribe. However, Iruruu quickly learns of the danger of her desirable position, and she's forced to take up arms and defend herself from competing factions seeking to kill and replace her. In this unfamiliar land, she'll question whether she's truly fit to become 'princess' in the court that resides over it.
