Is Monday, that means a new monster appears and UFO-Man will kick their ass. Classes ended for today and now you go hang out with your three friends Silk, Vivienne, and Tsubomi. You all go for ice cream and then see a giant monster with appearance of a toy appear nearby, your friends want to see the monster closer and so you follow them but they're crushed by UFO-Man's feet when he appears. Next moment you don't see UFO-Man anymore but a giant girl that reminds you of Silk, looking at you.
