Description
Melwin is a main character in the Catian alien crew, serving as the First Officer of the Catian Starship. Her official rank is the executive officer of the Catian Mothership, making her second-in-command directly under Captain Kunne. Physically, she is depicted as a teenage female with short, neck-length blue hair and matching blue eyes, and like all Catians, she possesses cat-like ears and a tail.

In terms of personality, Melwin is characterized as a strong and independent individual. She takes her duties seriously and demonstrates significant tactical ability, especially in high-pressure situations. This is notably displayed when Captain Kunne is incapacitated by enemy forces; as the acting Captain, Melwin must make a critical decision to protect her crew. When the Dogishuan Assistroids take control of the Catian mothership, she acts decisively by separating the bridge section and hiding it in hyperspace, thereby saving the command crew from capture.

Melwin's motivations are closely tied to her professional responsibilities and her loyalty to the Catian people's mission on Earth. Beyond her duties, she also harbors romantic feelings for the human protagonist, Kio Kakazu, placing her among the several female characters who become interested in him over the course of the story. Her key relationships include her professional dynamic with Captain Kunne, whom she serves under and temporarily replaces, as well as her interactions with the other Catian crew members and their human allies on Earth.

Throughout the series, Melwin demonstrates notable abilities related to her position. She is qualified to operate a mech suit in combat situations and is entrusted with command-level decisions regarding starship operations and crew safety. Her role in the narrative primarily involves supporting the Catian diplomatic and reconnaissance mission on Earth while responding to external threats from hostile alien factions. One significant moment of development for her character occurs when she is forced to assume acting command of the starship, showcasing her growth from a capable first officer into a decisive leader capable of protecting her people in the captain's absence.
