@EgoistJamal okayyy, rant time! If we're talking about a curiosity like Luffy's then heck yeah. Im a new watcher to one piece, I'm in the Skypiea arc! He does what he wants and doesn't stop till he does it and more, and even then he does the same things in all types of different ways to make it fun for HIM. There is nothing restricting him other than himself. There's no going the easy or the most taken direction. Fork in the road? He'll go through the wood in-between them lol. I won't call him the EMBODIMENT of curiosity nor anything close to NEUTRAL tho, cuz to me that means not having a moral compass and doing whatever without any consideration to others or even themself. Luffy cares and protects his friends and even strangers, he wouldn't allow he's curiosity to truly hurt those around him. Your character from your MHA fic, Kino, is also similar in this. I say he has a LOT more self control tho, but when he lets lose he's almost as bad as Luffy (chaotic menace to society...). But he is just one example I can think of for this concept among the many that are out there, and I'm sure you have your own unique vision.
