The late sister of Scarlet. She and her sister were members of a Nikke squad specialized in melee combat. Rose was also the original wielder of Fleetly Fading, Scarlet's signature weapon.

Upon realizing the nature of their squad where they are sent on numerous harsh missions in order to convert the last surviving member as a Grimms model, Rose incited a mutiny and murdered their former commander alongside other members of their squad who opposed the idea. Scarlet would eventually clash her sister in a duel, resulting in Rose's eventual demise.
