System S.E.X. (Seduction, Expansion, eXecution) - Chapter 279: High-Stakes Flirtation

In a world fractured by conflict and haunted by shadows of the past, Kokushibo—the first Upper Moon demon—meets his end, only to awaken in a new life. Reincarnated as Crimson, a child born into a different family, he carries the memories of a past he cannot escape. Burdened by centuries of guilt yet indifferent to the present, he resigns himself to duty—until an unexpected bond with his newfound family begins to thaw his hardened heart. As he struggles between the weight of his past and the weight of the new life, Crimson must decide whether he will remain shackled to his former sins or embrace the possibility of peace.

I, Hyoudou Issei, am a 2nd Year High school student and my age is equal to the number of years I haven’t had a girlfriend. And, someone like me got a girlfriend! I’m sorry buddies, I will walk the path of becoming an adult before you guys! – That’s how it was supposed to be, but why did I get killed by my girlfriend!? I still haven’t done anything yet! Are there no Gods in this World!? And, the person who saved me is the most beautiful girl in my school, Rias Gremory-senpai. I learned the shocking truth from her who isn’t a God but a Devil. “You have reincarnated as a Devil! Work for me!” Lured by Senpai’s breasts and treats, my life as a reincarnated Devil began. So the “Academy×Love Comedy×Battle Fantasy” starts here with just aggressive and worldly desires!

Ji Han, who was worried about his sister’s medical expenses, accidentally bound a money-making game.

The monsters in the other world, the puzzles in the film and television world, and the forbidden tombs in the legendary world.

Your game is too scary (love)!

What? 50,000 for completing the task? Kill a monster and give 30,000?

As an ordinary person, Ji Han shivered in the game, doing his best to complete the task to grab the head and get the much-needed monetary reward.

But in the eyes of others, he is the strongest alien warrior.

“Captain, the 10th team is really empty, they actually found a cowardly ordinary person.”

“Fart! All the monsters in the other world were killed by him alone. You fucking call this a cowardly ordinary person?”
