looking for help with the ranked skills

[Lt.Kitsune75]

First of all Hello! I like many of you am a fond lover of anime. and consider myself a 48 year old Otaku! now that being said I have come across a slight problem and am looking to my fellow anime lovers out there in the world and cyberspace to hopefully be able to help me. so her is my problem as well as request.

I have been trying to find a comprehensive list of Ranked skills used in the fantasy anime genre ( to include isekai). unfortuneatlyI have come across very little in that regard..... so I am hoping for anything that would give me a hand. mainly I am looking for a skill list using the letter ranking system up to SSS ranks. and if possible a brief description of said skills usage and pro  as well as cons that can come with those skills. ( to include limits on how many skills is typical from average everyday adventurer to Hero of the world/defeater of the -Insert Big bad of choice-)

any and all help and guidance would be greatly appreciated, even if it is to a little known table top rpg... just not DnD due to it not really having said ranking system

once agin thanks for any help as well as taking the time to read my humble...yet at the same time " Mount Everest" of a request
