One of the pilots of the G-Driller, and the more adept of the two.
Luna quickly establishes herself as one of the major annoyances of the series, mostly due to her mooning (get it? Luna=moon.) over Toga and his apparent disinterest in her. She always refers to him as "Mr. Toga". Which makes no sense because the dunce has literally no idea what marriage even is.
Luna has an attitude, and frequently makes her opinion known regardless of who happens to be nearby at the time. This tends to get on Eiji's nerves, and it should because Luna seems to make it her personal mission to make sure that Eiji is as miserable as possible.
Oddly, or not depending on what type of anime you prefer to watch, one scene involving Luna involves quit a bit of strategic censoring, this scene occurs when Toga is leading Eiji on a our of the castle, along the roof. Luna's bath room has a very large skylight right in the middle of the roof. Toga accidentally bumps Eiji off of the roof straight down the skylight, directly into Luna's bath, with her in it. Luna instantly freaks out and starts throwing everything she can get her hand on at Eiji. Toga comes to a rather odd rescue by staring down through the same skylight and yelling to Luna that it wasn't Eiji's fault, although this makes little differance to Luna in regards to Eiji.
Luna eventually loses out in the "battle" for Toga's affections to Leele and makes herself feel better by berating Eiji.
