Why do they keep killing him off? What did he ever do wrong? A fan of the otome dating game <Arlandast Saga> finds that her ultimate bias, Rumins, ends up dead in every route but one. After completing all routes of the game, a mysterious voice asks for her wish. Furious and choked up, she shouts to save her ultimate bias and to give him a happy life. <Your wish has been received.> Waking up as Senepin, the villianess who harrasses the main character, she enjoys her dream where she could talk to Rumins, alive and well. That is, until, ‘Senepin’ realizes that her new self was not a dream. Senepin remembers that the only time Rumins survived his damned endings was when he ended up together with the female lead, Belkina. Realizing this, she makes it her utmost priority to get Rumins and Belkina together. But for some reason, Rumins seems more interested in Senepin than the original female lead. Will ‘Senepin’ be able to save Rumins?
