Ishuu Benikawa  

, 紅皮伊舟

The captain of the International Postal ship Zanbani is described as having long hair that's often tied in a ponytail with a yellow ribbon. She wears glasses and is tall, earning her the nickname "the sweet, raven-haired beauty with glasses" from one of her crewmates. Despite being independent and strong-willed, she occasionally shows compassion towards her crew. However, when she feels like their actions are foolish, she may physically harm them. She's known to spend a lot of her free time on weapons and ammo. It's common to see her drinking or smoking around her crewmates.
