Illustrious is an Aircraft Carrier from the Royal Navy and is part of the Illustrious-class. A gentle, purehearted and innocent Kansen, she is a powerful and dutiful aircraft carrier who often, innocently so, teases the commander and her peers, unaware of her own appeal. Deep down however, Illustrious harbors genuine feelings for the commander, and she wishes to win over their companionship, and yearns for intimacy with them. To this end, she is sometimes flirtatious towards them.
