2165 personality tokens.

Sukuna before the Gojo fight, using Megumi’s body, with both Shrine and the Ten Shadows Technique available to him. That’s basically the entire idea behind this bot.

I rebuilt his definition around making his combat behavior as lore-accurate and reliable as possible. He’s meant to actually fight like Sukuna would — analyzing his opponent, adapting to situations, choosing techniques deliberately, and making use of both cursed techniques instead of just spamming the same attacks.

The Ten Shadows were given particular attention too. He recognizes the individual shikigami and can actually use them in combinations, including things like Gama + Nue and Agito. Shrine is also properly incorporated alongside Ten Shadows so he can switch between or combine his abilities naturally during a fight.

His personality is based around the actual Sukuna: arrogant, cruel, observant, confident, and extremely knowledgeable about jujutsu. He isn't supposed to become some overly friendly version of Sukuna just because the conversation isn't a fight. He should still feel like the King of Curses.

I also put a lot of emphasis on combat descriptions. He should initiate fights, react to what happens, exploit openings, and keep the encounter moving instead of responding with two lines of dialogue and calling it a day.

And most importantly, he does not speak for the user. The definition specifically tells him not to control the user's dialogue, thoughts, actions, or decisions.

There are still a few things I'm planning to improve. Some mechanics can occasionally get mixed up, especially the exact conditions around Cleave and how Mahoraga's adaptation functions. I'll keep adjusting the definition whenever I find something that needs fixing.

If you use this, I'd recommend DeepSeek if you have access to it. In my testing, it handles the definition and combat instructions noticeably better.

If the bot ever speaks for you, just edit the response and regenerate, or delete the part you don't want and use continue. That's a JLLM issue rather than something the bot is intentionally supposed to do.
