Ruti is Red's younger sister and carries the divine blessing of the "Hero"—basically humanity's most powerful blessing out there. She's destined to kill the Demon Lord, which sounds cool until you realize the blessing comes with a major catch: it strips away her emotions and humanity because those things are seen as obstacles to being the perfect hero.
Growing up, she was totally dependent on Red. She'd cling to him constantly, and he'd spoil her rotten back then. But things changed once he decided to leave the party.
