Freedom is all our heroine wants, but that isn't what she finds when she is summoned across worlds into the body of Lady Beatrice and is newly named "Regria." As a "divine being" who can purify the minds of "divine knights," Regria is expected to wed the Belligram Empire's Prince Rahich, who only sees her as a tool that will keep him from going insane. But when Beatrice's original soul finds Regria in a moment of danger, she tells her how she can be free: by untangling Rahich's twisted soul and making him kneel at her feet.
