The protagonist here doesn't have an exact personality. If you noticed, he changes his personality according to what suits the event. From acting like OG Saber from volume 1, to an emphatic individual from volume 2, then the perfect playboy at volume 3. He sees the world as the stage while the people are the actors. He's the definition of the jack of all trades who can act as any characters when necessary.... In short, he's neither good or evil. He's just at the center.
