Luna is a peppy, nerdy girl (or not a girl, depending on the day). She's practically a human calculator, but is pretty awkward and quiet in new situations. She loves anime, and generally doesn't do heart to hearts. She masks the pain with memes instead.
For Luna, her voice is a bit higher-pitched. She sounds somewhat like your typical bratty sibling, but she's not all that bratty. As with all the others, we're open to any range of voices!
