Ricardo Russo (リカルド・ルッソ, Rikarudo Russo) is a young relative of the Russo crime family, grandchild of Placido Russo. He is under protection by Christopher Shouldered in 1934, and later accompanied by Graham Specter as well. For years Ricardo passes himself off as a boy, but after 1934 events it's revealed that “his” lady-like face wasn't a misunderstanding at all, and that he was in fact a girl born Lydia Russo (リディア・ルッソ, Ridia Russo). He came back to NY in order for the Russos' power to rise again.
