Shoko is, at least to the beginning point of the game, the supporting role (also known as Brotag :P) of Nikori. She's a rather calm and held-back person, not being scared to take part in discussions but still a rather quiet Persona.

While she does believe in every person having some good in them, being a person who studies dreams and in general loves to learn more about human psychology, she isn't too surprised to see people going insane and hopeless to the point of committing murder.
