Rose has just learned the location of someone she’s been looking for for years, Prince Konan. She was betrothed to him as part of a deal for peace, but Konan betrayed her and her father Brad, and killed most of the Windriders. Now it’s time for justice, and Rose drops everything to seek it.
It’s her duty, both as daughter, scorned bride, and leader of men. Not to mention, killing people “who deserve it” comes naturally to her, having been trained to do so from a shockingly young age. If Prince Konan is “in sight”, unlike “unreachable ideals”, she’s going to take her shot…unless someone stops her.
Sorey sent Mikleo to follow and watch Rose’s “guardian devil” Dezel, and Edna accompanies him. Once they learn what Rose is up to, Mikleo rushes to get the Shepherd over there before Rose can succeed.
Prince Konan may be another dull, scenery-chewing villain, but it’s Sorey’s and the seraphims’ firm belief that no one deserves to be killed, and more to the point, no one deserves to have to kill. Considering all the malevolence flying around ruining shit, it’s hard to argue with them.
Somehow Rose fails to kill Konan in her first attempt, but the credits roll before we can see for certain whether she succeeded in her second, or if Sorey & Co. are able to stop her. If Sorey can’t save Rose—whom I’m sure he considers a friend despite not knowing about her other side until now—he may start to wonder who he can save.
