Hanako Eiko is a Plain-looking girl that likes to play games to relieve stress. The only problem is that she goes a bit overboard when playing, to the point that she got to be called “Annoying Pest” by most of the players from the online games that she plays. Eiko was forced to participate on a Field Trip from School since she is a parasite at home. While in the way towards the place where the Field Trip is supposed to be, Trush-san appeared, just joking.
