I'll go with my personality representatives as well. Watching Fairy Tail has allowed me to reflect on myself and understand what sort of person I want to be. What sort of person I am currently. There may be many other characters I can relate to oder I have a strong admiration for but Erza Scarlet along with Saber, Ryougi Shiki and Nico Robin really deserve recognition in this regard.
"All I need is the power to be able to protect my comrades. So long as I can have the strength to do that, I don't care if I'm weaker than everyone else in the world." Erza Scarlet
"Everything in existence has a flaw. Not to mention humans, but air, will, and even time. It's natural to have an end if it has a beginning." Ryougi Shiki
"Fools who don't respect the past are likely to repeat it." Nico Robin
There are many. Each of my Favoriten have AT LEAST one aspect I cannot help but admire / get inspired from.
And going once again with Medaka Kurokami for this type of Question. The kind of Personality that inspired me ever since I first got to know her and that is going pretty back during the days I was just getting introduced to Anime and taking into consideration the concept of Relatable Characters in general. One main reason she has become a Favorit of mine is that she has been representing my Growth and Improvement and keeps doing so. It is something I say with Pride as Medaka is exactly what I consider an example to take from either way !!!!
