Ooooooo...
Do something new, do all of the above!
Something never seen before, idiosyncratic to a cyberpunk character in a medieval fantasy world. Yup yup.
Indeed, having all three mixed together to create an interesting method of torture.
Based on your request, the method of torture should be:
1. Painful
2. Novel
3. A combination of physical and psychological
Let's design a torture method that incorporates all the above elements:
1. The slow shaving method
This method involves the use of only one item, a shaving knife. We do not use it to slit someone's wrist or neck. All it is used for is to shave. At first, we shave their moustache, then their beard. Sounds innocent enough? Then we shave their heads. Is it still nice and innocent? Now we strip him naked, we then shave their legs, making it very clear to them that we don't care about being 'careful'. So by the time we're 'done' with their legs, there would be so many open wounds. But poor guy, it's no good to let his wounds get infected, so let's wash his wound, with salt. Do use solid salt, not salt water. We don't want him to be too comfortable. Then we start work on their... privates.
2. The irritating method
This method does not physically harm the victim. What it does is make him extremely irritated that he would agree to spill everything just for it to stop. The problem with this method is that you need to know exactly what would irritate him the most. You can also play on the person's phobias. For example, if he is afraid of heights, hold him over a ledge. If he hates the grating sound of chalk on blackboard, use that. If he hates the voice of Cardi B, make him listen to her songs. The possibilities are endless.
3. Torment and promise
This method can be outright cruel. Let's say a man has a threshold of pain that he can handle, and beyond that, they will blank out and becomes unresponsive. But what if the pain is not on him, but on another person, someone he has deep feelings for. In this method, you do not torture the man, you torture his family, especially if his family is someone he loves. Any family man would fold and speak the truth and only the truth for the promise of his family's release, even if he himself doesn't survive afterward.
If you want, Ai-chan can suggest:
1. The actor that would best fit the role of torturer
2. The actor that would best fit the role of the victim
3. The actor that would best fit the role of melon eater
Just tell Ai-chan.
