I mean, its creative. Let's just hope you build up the verse well since well most of the characters seems to have a different backstory (based on how much I've seen). Just improve the writing quality and that's it, I guess.

I actually thought about using firearms at first, but then another idea crossed my mind and told me to use this idea for later

The ability that Sasuke is basically his deciphering ability that he possesses in the boruto most basically the novel version of it. Also yeah Sasuke and Riku are basically twin

to be honest if we put a prime un-nerf sasuke, it would be broken as heck. Sasuke gonna have limitation, so that he doesnt one shot the story and ends it in one chapter
