Nina

Nina is perceptive, conversational and highly attuned to the thinking of other riders. Rather than simply watching a battle unfold, she analyzes tactics and considers what choices she would make under the same circumstances.

Her habit of casually commenting on Kilik's strategies can irritate Shiraume Noyamano, particularly when Nina's detached analysis seems at odds with Ume's emotional investment in events.

She remains calm even around the extraordinary riders gathered within Sleeping Forest, suggesting considerable familiarity with high-level A-T combat.

Nina operates a full-body A-T suit that dramatically changes her apparent size when closed. The equipment appears designed for both protection and synchronized movement, allowing her smaller body to control a much larger combat frame.

Opening the suit allows Nina to generate a defensive effect resembling Yoshitsune's Rumble Wall. The technique manipulates air pressure into a protective barrier capable of resisting attacks.

Her exact Road and King title are not explicitly established in canon, so identifying her outright as the Rumble Queen would go beyond what the manga confirms. Her demonstrated techniques nevertheless show clear similarities to Over Road applications.

Nina appears as part of the generation of Sleeping Forest that protects the Trophaeum after the original team has disappeared. She is seen around Kilik and the other riders responsible for guarding the tower and observing developments in the Storm Rider world.

Her commentary helps explain the mechanics and tactical implications of Kilik's Gaia Road during complicated battles. Rather than serving primarily as a direct antagonist to Kogarasumaru, she often functions as an informed observer within Sleeping Forest.

Nina later participates in the defense of Sleeping Forest's position as the conflict surrounding Genesis and the Sky Regalia reaches the Trophaeum. Her A-T suit and pressure-based defenses give the team another specialized capability alongside its established Kings.

Kilik is Nina's leader in Sleeping Forest. She understands his Gaia Road tactics well enough to analyze his decisions and imagine how she would approach the same situations.

Shiraume Noyamano is another Sleeping Forest member with whom Nina interacts while observing battles. Nina's analytical comments can irritate Ume.

Ringo Noyamano is Sleeping Forest's Thorn Queen and one of the principal riders Nina supports as part of the same team.

Mikan Noyamano is another member of the current Sleeping Forest and one of Nina's allies in protecting the Trophaeum.
