Who Created The First Death Game Manga?

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: “???”

Willa Roane dies the same night she catches her boyfriend in bed with her sister. Instead of waking in peace, she’s dragged onto a ghostly bus and informed—by a mocking intercom—that she’s entered the Survival Game: a twisted show where the dead are thrown into lethal, terrifying worlds for the cruel amusement of an unseen audience. The rule is simple: survive each round… or your soul is erased forever. Her only ally is Corvin Thorne, the devastatingly beautiful stranger who yanked her off the road and onto the bus. A hybrid vampire–werewolf with a past soaked in blood, Corvin is bound by a wicked secret contract to keep Willa alive… or forfeit his own soul to the game. As they descend deeper into the nightmare realms—from a monster-ruled Dracula Castle to ruined neon cities—Willa realizes she is the key. The deadly worlds are twisting around her darkest fears and fantasies, turning her own horror stories into elaborate traps. She isn’t just a player; she’s the author of the chaos. And the man sworn to protect her may be the only thing she can’t control. Now Willa must rely on the dangerous man she’s falling for, a man who swore he would never love again. The heat between them is undeniable, but as their bond deepens, it’s impossible to tell which is more dangerous: the monsters hunting them… or the love that could destroy them both. Love might be beautiful—but in this game, it’s never sweet. It’s a weapon, a weakness, and the one thing that might rewrite the rules of Hell itself: desire. ---

He was a Kung Fu head trainer, who was framed by his two trainees in a rape and murder case of Clushia, a female trainee, who was obsessed with him. He was convicted and brought to the maximum penal institution called the 'Hellhole', for no prisoner got out of it alive. In one of the prisoners’ riots, he was forced to fight to defend himself but ended up killing another prisoner. He was put to an oubliette. Unknown to him, that oubliette is the door to an underground city, with an arena for the so-called “Game of Fangs and Death” by the Alpha Pharoah. The game is for five nights. If he wins, he will be given a free pass leading to a secret passage, away from the 'Hellhole'. Could there be an escape for him from the 'Hellhole'? Could his heart find an escape from the Alpha Pharoah's daughter, who has a lot of similarities to Clushia? It was like, Clushia had been born again through her. Would suddenly his never known powerful blood and lineage eventually help him escape from his death?

I've chosen to participate in a death game. As long as I can escape from the murderer's killing spree in ten time loops, I'll be able to win at least 100 billion dollars. In the first loop, I have my apartment refurbished into a bank vault. Still, the killer is able to bust down my front door. In the second loop, I hide in the ceiling crawlspace. Yet, the killer is quick to locate me immediately, as though he knew where I was, to begin with. In the third loop, I finally realize that something's definitely fishy…

The Horror Game invaded the world. Real players entered the game, and their every move would be broadcast live. My adopted son shoved me—an eighty-eight-year-old woman—straight into a deadly dungeon to save his own skin. One of the comments in the live stream predicted: [What? They’re tossing in such an elderly woman? No way she’s gonna survive the first night!] On the first night, a frost-bitten ghost exhaled icy breath in my face. I shrugged off my thick floral coat, feeling sorry for her. “You poor thing! You must be freezing. Listen to me and bundle up quickly!” The second night, a starving ghost lunged at me with blood dripping down his chin. I sniffed the air, then found a jar of pickled cabbage. “Look at how skinny you are! Come on, let me get you something hot to eat.” On the final day, the last surviving players tied me up, desperate to steal the one ticket to escape. However, before they could touch me, every ghost in the dungeon came storming out, cleavers and rolling pins in hand. “Touch her, and you’re dead meat!”

My roommate sets me up. She deliberately forces me into a death-trap survival game. As I shut my eyes and wait for death to take me, I realize that the game's bosses can read my mind. "Look at the blood spurting from this baby doll's neck. It's like a fountain of pee." The baby doll is baffled. It's about to launch its ultimate move, but it falters. "Man, look at how this guy is still sweeping the streets when he's so old. Does he not have a pension?" The old man is about to swallow me whole, but he suddenly gets a heart attack. An ambulance takes him away. "Oh, so this is the amusement park's owner. Oh, dear god, he's handsome, albeit a little skinny. I can send him flying with a kick!" The handsome owner's expression darkens. He instantly takes off his shirt to reveal his washboard abs. "Do you still think I'm skinny?"
