Isn't that every one
Erza lived in a tower for her childhood and got hurt a lot then when ever she was able to escape he took her friends and told her if she tells anyone he will kill her friends (trying so hard not to spoil anything)

Natsu didn't know his parents and when he meet igneel , was his adoptive father . But then igneel went away

Gray lost his parents to deleora (or how ever you spell it's) then ul his teacher to who saved him to stop deleora turning into ice.

Lucy mother died and her father abused her in words getting mad at her and taking all her money

So everyone

Next character i wished was real
