Hi!

Ive read the start of a manga or cartoon (idk know which it actually was) when I was ab 12 and the dumb me didnt save the name or app...

So i need help finding it 🙃

Its a manga about a wise old man getting reincarnated as a little boy and in thz wolrd that he now lives in everyone has a soul thingy and a weapon. Most ppl have things like knives but the main charater had the most useless, common one (a vine) and everyone made fun of him until they saw his soul rank which was insanely high. Theb they flashforward to when the boy is ab 17 and meets somekind of bunny girl and they go to a school.

I havent read further and the details are fuzzy but I would rly like the help if anyone knows this 😔
