if i had a nickel for every time i read a series where the most powerful exorcist was killed and he reincarnated in another world where he was looked down upon for his low magical talent, but his exorcism powers made him the strongest anyways, i'd have two nickels, and that's fine with me
second one is alternatively titled "reincarnated as a son of an aristocrat"
Bro you won't ever stop counting nickels when you change the description to "I got reincarnated and people make fun of me because I am weak. But actually I have a secret super strong skill that makes me the strongest"
I've recently gotten into "people make fun of me because I'm super weak but I'm actually the best in my field and people just don't realize the importance of my role, and after I got kicked out of my party they discovered that they became much weaker and were initially in denial but they will soon be begging on their knees for me to come back, but I've already found other people who actually respect me and what I can do"
wow that sound so unique
