Akutoku Kizoku no Seizon Senryaku
I was reincarnated as the protagonist of a game I had been playing, "Survival Strategy of a Rogue Nobleman," and I immediately had to fight to survive. Thanks to my parents' foolish rule, the territory was in shambles and on the verge of rebellion. Even if I could have avoided this, I would have been dismissed by the royal family, a brave warrior would have risen up against me, demons would have attacked, and many other doomsday endings were going to occur. I can't even trust my personal maid or the family butler, who are supposed to be my allies, even as my last-ditch battle is about to begin! All in order to make it to the good ending with a life of luxury!
