Emperor/Prince Larsa Ferrinas Solidor! (Which is why I am going to cosplay him!)
Otherwise the second place is a tie between the Fon Ronsenburg twins Basch Fon Ronsenburg and Noah Fon Ronsenburg (known as the original Judge Magister Gabranth).

I mean the young (now) Emperor ran away from his guards, quickly made up a false alias, threw Manufactured Nethicite at a notorious Headhunter, ran faster then anyone else from the Lhusu Mines and felt that he had to help Penelo.
Not to mention he still has the title of Potion Prince.

And the Fon Ronsenburg Twins are just amazing, both skilled fighters, both have royal duties to both main royal bloodlines (excluding the Margace bloodline) and both will give anything to protect their friends and for peace.

I mean honestly, there is no way that I cannot see these men as my favorites.
