After traveling to the world of Honkai Impact 3rd, Lin Xi is bound to a "Seele Simulator." By successfully conquering or rewriting the fate of plot characters in various simulations using Seele's persona, the host will receive character-specific talent rewards. However, if the simulation's evaluation is too low, the host will not only be locked out of the relevant scenario, but will also be forcibly bound to some "strange" talents after the simulation ends. As the simulation progresses, one beautiful girl after another falls for Lin Xi's Seele persona. So... Alicia: Seele, when will our wedding be scheduled? Mebius: Let's do something fun, sweet little Seele. Big/Small/Honkai Impact 3rd: Seele! Bronya finally found you! Let's get married! Kiana: Seele is truly gentle and adorable! Lin Xi, while posing as Seele in the simulation to reap the benefits, is completely unaware that she has completely taken on Seele's form. Lin Xi: You're looking for Seele, what does this have to do with me, Lin Xi? Until the object in the simulation, and even the real person in the quantum sea, came to force a marriage...Lin Xi: I'm so excited!
