Nepgeo (ネプギマ,Nepugima?) is a minor NPC that lives in Planeptune. She looks like Nepgear, but is very crude. She will tease and insult the player if they attempt to chirper with her. She also has an ASIC colored clip in her hair.
It was rumored that she was possibly Linda in disguise. However, Nepgeo is still present in the Conquest Route after Linda is killed off.
Her original name is a reference to the Neo Geo, an arcade system and home console released during the same generation as the Genesis. They both had a large library of arcade ports. Neo Geo also released a portable version known as the Neo Geo X in 2012 which shares some minor level of visual similarity to the Sega Game Gear.
