Who Is The Main Antagonist In 'Ero Trap Dungeon'?

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.

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.”

I'm a succubus who gathers energy by clearing System missions, adept at the game of love. One day, right after completing a honey trap mission, I was sent to a SSS-level horror game at the very next second. The boss was invincible and bloodthirsty, watching coolly as other players rested in pieces before turning to the rest of us. "Now choose—how do you want to die?" While other players were wetting their pants and trying to find a loophole to survive, I picked up on something different. A handsome, powerful target beneath that cold, horrific exterior. Hence, when he reached me, I smiled enigmatically as I told him my wish. "I wish to be conquered by a truly powerful Entity, dominated from soul to flesh, and to die in pure ecstasy." I watched him pause in shock and added, "Oh, and you must do it yourself."

The Pentarchy famiglie forbid their heirs from marrying commoners. But Matteo Adorni loves me so deeply that he plays revolver roulette against his father just to be with me. Even as blood soaks through his shirt, he still holds me and smiles softly. He says, "Don't be afraid, Rosella. Only death can separate us." But later, he secretly sleeps with Giorgia Vitalis behind my back. When I discover this, he explains guiltily, "The price for the famiglia allowing us to stay together is for Giorgia to give birth to my heir. Please wait for me, okay?" After that, he sleeps with Giorgia 33 times, and they have a daughter. However, the heir must be a boy. So, he sleeps with Giorgia another 99 times. This time, when Giorgia becomes pregnant again, she tearfully accuses me of poisoning her unborn child. Matteo points a gun at me. "Why are you trying to kill Giorgia? Why are you trying to kill my child?" I am chained inside the Adornis' dungeon. All I can do is beg day after day. Finally, the dungeon doors open once again... This time, I will not wait for him anymore.

My roommate was obsessed with those cheesy “milk-scented girl” romance stories. She wanted to become the kind of heroine from those books. Tiny, soft, and delicate, the type who was supposedly so sweet that even her farts smelled like milk. So she went completely overboard. She lived on dairy. Drank milk nonstop. Even took milk baths. She tried everything, all because she was convinced she’d eventually run into her destined male lead. I believed in letting people make their own choices. What I didn’t expect was for her to go after my boyfriend, the guy I’d basically grown up with. One day, she sent him a carefully posed thirst trap. He replied with one word. “Get lost.” Then she proudly showed me the screenshot, like she’d won something. “Only girls like me, soft and sweet and irresistible, deserve a powerful man’s obsessive love.” “Don’t be fooled by how cold he is now. He’ll be crazy about me soon enough. He’ll want me all to himself.” I was just about to tear into her when a row of floating comments suddenly appeared in front of my eyes. “Fresh one, guys. This host is bold. Coming in with a thirst trap right away? Nice.” “Wait, what? Isn’t this just harassment? The male lead already has a girlfriend.” “Bro, I think you’re in the wrong livestream.”
