A few months later, informally calling themselves Team RNJR (pronounced "ranger"), Ruby travels with the remaining members of Team JNPR to Haven Academy in Mistral in order to find leads on their enemies. During their travels, Ruby is targeted by Tyrian, but she evades capture with Qrow's help. In Volume 5, Ruby trains in hand-to-hand combat under Ozpin's guidance. She also unexpectedly reunites with Weiss and Yang. During the Battle of Haven, Ruby activates her silver eyes again, affecting Cinder momentarily, but she gets knocked out by Emerald. After she recovers, she and her allies win the battle. Ruby and her teammates then reunite with Blake.
