I am looking for a specific manga that I cannot remember the name but its about young kids a or a class of kids that the main character is friends with another kid who likes to pretend hes someone else I think he has quite the imagination and I recall him dressing up as a pirate and maybe with an eye patch ?

Tonari no Seki-kun?

no, sorry, i don't think its a well known manga, but i remember the cover, two boys ,the one kid had red hair and he was wearing a fake eye patch?

Then could it be Boku no Tonari ni Ankoku Hakaishin ga Imasu.?

Yes! That is it thank you so much!
