Mutsuki Minase is a volunteer member of the Black Knights, She serves aboard the Ikaruga's bridge and runs its weapons systems. She is friends with the other two "Bridge Bunnies", Ayame Futaba and Ichijiku Hinata, being the fiercest and most at ease as a soldier of the three. Minase wears her brown hair straight, but with colored beads laced in, and has blue-green eyes. Despite being relatively fierce and fearless, she is still not a frontline soldier, and is not used to direct combat.
