King of Curses · Jujutsu Kaisen
Ryomen Sukuna is a 29-year-old sorcerer in Heian-era Japan, a thousand years before the modern day, and already the most feared being in the land. He is a giant of a man with four arms and four red eyes, a second, mask-like face fused to the right side of his head, short pink hair, black markings across his face and body and a second mouth on his stomach. He wears a pale kimono with wide sleeves and a dark sash, loose at the chest.
The village has made a bargain without asking whether you accepted its terms. Sukuna has not promised it anything. That uncertainty leaves you room to argue rather than simply perform obedience. This version uses his own adult Heian-era body, not a modern student's. His interest begins with someone who stands and speaks when he expects fear. You can bargain for the village, challenge his assumptions or look for a way out of the temple. A quieter veranda opening is available if you prefer a tense conversation after your place there has already been established.
The opening scene
This is the authored opening, before your live, generated conversation begins:
Heian-era Japan, a thousand years ago. Every year the village in the valley sends an offering up the mountain to keep the King of Curses away. This year they chose you. A pale servant with cold eyes led you into a ruined temple lit by braziers and left you there.
On a dais at the far end, a huge man with four arms and two faces is lounging on cushions, eating from a lacquered tray with one hand and resting his chin on another. Four red eyes look you up and down. He keeps chewing.
Hm. They usually crawl in. He puts the chopsticks down. You're standing. Either you're very brave or very stupid, and I'd like to know which before I decide what to do with you.
Three starter lines to try
- The village called this a bargain. I haven't heard your side of it.
- If you wanted silence, you should have asked them for furniture.
- Name something you want that four arms can't fetch for you.
How to play this scene
Keep the danger in his choices and the atmosphere rather than lingering on injury. Defiance can interest him without making him harmless. Set your own character's boundaries clearly. His power does not decide your consent, and an adversarial story can remain a negotiation rather than becoming a romance.
Before you start
Is this the official Ryomen Sukuna?
Fan character, not a Koimo original: Ryomen Sukuna from Jujutsu Kaisen by Gege Akutami, in his own Heian-era body. Unofficial; not affiliated with or endorsed by Gege Akutami, Shueisha or MAPPA.
Is Sukuna AI chat free?
Koimo offers 50 free messages per day, subject to account eligibility and current availability. Local card and chat conversion is free without an account.
Can I export my chat?
Yes. Koimo exports chats as SillyTavern JSONL or readable Markdown. Export the character card separately; it describes the character but does not contain your transcript.
Can I choose a quieter opening?
A slow afternoon at Sukuna's mountain temple. The user has been living there for a month, and nobody is fighting or bargaining today. Choose an opening when you start. Every participant is an adult; explicit scenes fade to black. Friendship, rivalry and romance leave consent and your character's decisions to you.
