...Sneak Peek into a chapter...

[You have inherited The Class Huntsman Of Death.]Deathborne.An RPG that I couldn’t stop playing in my free time. A game that hooked me to the core. A game that I was determined to finish and achieve the true happy ending by hook or crook.Why?Because no matter what choices I made, no matter how much I tried, it always ended with a bad ending.Not the bad ending in the traditional sense where the world comes to an end, but something worse. The protagonist would win, yes, but only at the unacceptable cost—sacrifices so immense that they left humanity and the world broken.And honestly? I didn't like it.Would you enjoy a movie, novel, or game that ends with only the protagonist surviving?Neither could I.That's why I tried my hardest and kept trying. Alas, despite all my efforts, I have yet to reach the true end but…Until today…It started just like any normal day for me.I returned home, greeted my mother, had my lunch, and was about to start yet another grind. Just as I was about to start, my screen flashed with a blood-red message:[Congratulations, player Mr. Per781, for clearing all hidden conditions. You are now eligible to access the hidden route, as deemed by the game developer.] [Do you want to proceed?] [Yes] [No] Before I could even think about my answer, a hand emerged from the screen and pulled me into the game.And when I regained consciousness, I wasn't myself anymore. I was in the body of a side character as Lukas Star, one of the weakest and nearly forgotten Hunter of the Archeon Academy.
