If that commentary MTL is right... Neptune's basically the direct opposite of Sheffield... a smiling girl with a really venomous tongue
This is the translation I saw in the discord:
Light Cruiser - Neptune A fictional realization of a light cruiser that only exists as blueprint designs. While her speech is elegant, she has a devilish personality, always teasingly looking down at the commander. She is a waitress who is also a pâtissiere. She is not a maid (this is important).
