1. [Time Skip]: I will be getting straight into the main plot of JJK season 1 and season 2, meaning Kuro will be in academy with Nobara, Megumi, and Yuji Itadori as well as all the other young sorcerers of this Era. This way you will see Kuro grow his power at a faster rate and see how he will effect the future plot of JJK world.
2. [No Time Skip]: Kuro be training his powers young with Gojo, his two sisters 1 younger and older and of course his Mother which I will give them names next chapter! During this time it be will the Star Plasma Arc so you will see all the characters there like Riko Amanai which you know what tragically happens to her in anime [ but maybe things change in this fic?]
3. A [small time skip] which has both of the above^ this my favorite choice.
Anyways go vote by commenting in the paragraphs above or comment in comment section!
