Neptune is the CPU of Planeptune, a nation in Gamindustri. She was summoned to this world for some reason. Her happy-go-lucky attitude and overall personality are set to full throttle as usual. She has visited many worlds and dimensions before, and this time, it looks like she's teaming up with the girls of this world in order to offer them her full support.
Belfast asks Neptune to introduce her to popular dishes from Planeptune. "Uh, we had popular dishes?! Um... Oh, I know!" What kind of crazy things is our beloved CPU going to say this time?
