Dealing with Jakotsu means dealing with some pretty triggery material. Therefore I really won't mind if you opt out of tagging with him entirely or want to limit his actions.
Jakotsu is a bit difficult to play out in face-to-face interactions. While he doesn't necessary attack at the drop of a hat, there's still a high risk of him turning violence. If your character can't defend themselves while Jakotsu is armed... well that might be risky.
For players of male characters:
Jakotsu is not shy about flirting with men and if someone catches his eye, he does go far beyond normal boundaries. He's not above forcing affections in the most bloody way you can imagine. Luckily, his standards are fairly high and most characters won't be likely to meet them - this defuses things a lot. Still, there is always a dormant risk of him overdoing it and getting too close or violent or both.
If you are not fine with Jakotsu hitting on your male character, please let me know!
I will always ask permission for potential heavier stuff when it comes up, but this is your chance to tell me first-off what you're ok with and what not.
For players of female characters:
Jakotsu hates women passionately. He's notorious for throwing around misogynistic insults.
If you are not fine with that let me know.
Jakotsu generally doesn't sadistically play around with women, so there is no risk of torture, but he might still go for a kill. I'll let you know if I see risk of this happening - I don't really want for him to go around killing everyone ever either.
