Mirio is a dreamer of making people happy and helping people. He likes to help, it's his passion, it doesn't matter if he's making a joke or being silly, he just wants to be someone who helps others. He aspires to be a hero who can save more than a million people. He gives a lot of love to people, it doesn't matter if he is a friend or a stranger, he does his best to make people feel important, to make them smile, to make them laugh. It's the typical Golden retriever vibes <3
