How Does The Gacha System Work In 'Gacha Summon'Em All....And Yandere Too'?

I’m the heroine in an erotic story. My specialty? Turning anything hot or cold into something steamy. On the first day I landed in a horror game, the boss told everyone to choose how they wanted to die. I smiled and said, “I’ll take shortness of breath, trembling legs, glazed eyes, and… pleasure so intense I die from it.” Boss: “???”

I woke up as the Villainess, but instead of a halo, I got a Scythe. However, my power has attracted the world's most dangerous monsters: A possessive Werewolf, a bloodthirsty Vampire, a Tentacle-wielding Professor, and a Biblically Accurate Angel with a thousand eyes. They think I'm their prey to be tamed, but they forgot one thing: I am Death itself.

When the apocalypse came, she lost everything. Starving, hunted, and desperate, she trusted the one man she loved… only for him to betray her in the cruelest way possible. He stole her last supplies to please another woman and left her to die in a sea of the undead. But death wasn’t the end. She woke up days before the world collapsed. After cutting ties with her ungrateful ex and his parasitic family, a mysterious voice awakens in her mind, LUS, a Level-Up System designed to help her survive the coming end. With knowledge of the future and a system guiding her every move, she begins to prepare. She stockpiles resources, builds a base, and learns how to fight back against the horrors that once destroyed her. And when the apocalypse arrives again… she’s ready. But survival isn’t the only thing waiting for her in this new life. A silent killer who watches her like prey. A manipulative genius who wants to unravel her secrets. A gentle protector who sees the girl she hides. And a dangerous man who thrives in chaos. As the world burns and power shifts, they’re all drawn to her, each with their own motives, each with their own darkness. Even her past refuses to stay buried. Because now, the man who once abandoned her is back, broken, desperate, and begging for a second chance. Too bad she has no time for regrets. Not when she’s busy rising to power… and building a kingdom in the ruins of the world.

[YOU HAVE TRANSMIGRATED INTO A VILLAINESS FATED TO DIE.] I was supposed to obsess over the Alpha King, scheme against the heroine, and meet my end at the execution block. Instead, I rewrote the story. I chose Pierre Ashbourne—the neglected second male lead I once pitied as a reader—and spent three years helping him rebuild his dying pack, believing I had finally changed my fate. Then he abandoned me at our mating ceremony for his first love, the heroine. Now, the system has given me only one way home, restore the original ending by pushing the heroine back into the arms of the ruthless Alpha King, Hades. But the more I try to complete the story, the more these leads are getting out of character! What should I do?

I transmigrated into a dating-sim otome game where I was supposed to romance a soft, fragile male lead. I had finally pushed him onto the bed and was just about to make my move when the long-missing system finally popped back online. [Host, I sent you to the wrong game. This is a horror game.] [The man you’re bullying right now is the horror game final boss.] I lifted my head and met a pair of blood-red eyes staring straight at me. My smile froze. “Um… you look a little tired. Maybe we should… continue this another day?” He smiled back, calm and terrifying. “I’m not tired. Go on.”
