Thanks for the chapter, so far it looking amazing. If you need any inspiration for things like cursed spirits that isn't from JJK have a look at the Webcomic The Gamer since it had a few things very similar, along with things to abuse and benefit said events. Also, just an idea I think you could give the MC Parseltongue, but not as a technique but as a Gift, like how The Six Eyes aren't a technique just a powerful physical mutation, and maybe make it a little more useful instead of just talking to snakes, like the ability to command any snake real or spiritual or the power to amplify any spell or technique is used in. Anyways these are just ideas I'm sure you've got something in mind and I can't wait to read more :)
