As a transmigrator in the perilous Ultraman universe, Yuan Ming has only one goal: survive. A hero? A good person? Whoever wants the job can take it. You say I'm an Ultra Warrior? Sorry, I'm only a light-and-dark giant, and even that is just one of my powers.
The protagonist isn't a self-sacrificing saint. You could even say he's so self-interested that he's cold-hearted. He's never been a hero, doesn't want to be one, and doesn't hold himself to the standards of a good person.
