A reliable and serious character whose cold exterior masks his weaker, gentler self, Shinjiro's difficult past weighs him down, causing him to constantly push others away with a tough-guy act. Ever since accidentally causing the death of Ken's mother, he has given up being a member of SEES to live a normal life, even though there are only so many Persona-users and so SEES needs all the help they can get, something even Yukari, who has no love for SEES or the Dark Hour, has the sense to realize. As he points out to Akihiko, both of them are held back by the guilt of their pasts; they just have completely different ways of dealing with it. (taken from SMT Wiki)
