“When I woke up, I found myself reincarnated as the mid-boss of the tutorial of the epic RPG ‘Spirit War Dungeon Magia.'” “But I’m not just any mid-boss.” “My abilities are modest. My performance is lackluster. And my catchphrase is ‘Hyahhaaaaaaaa!'” “Not only do I lack companions, but I don’t even have friends. On top of that, I have the incredible misfortune of always dying in the tutorial. I’m nothing but a pathetic bottom-tier boss.” “Of course, I know that my own future is not too bright. Furthermore, I have learned that my beloved sister is fated to die from an illness.” “Big Sister, I’ve made up my mind. I will crush all the unfair conventions of this world in one fell swoop.” “With my vast knowledge of games, I have decided to rebel against the established history.” “And so, as I ‘conquer’ the strongest hidden boss and the most traumatizing route boss in the game… I will grow into the leader of the ‘monsters’ that inhabit this world.” “Conquer the enemies of this world and ‘conquer’ all the unfairness.” “This is the story of an extraordinary party full of boss characters, a ‘what if’ tale that begins now.”
