One morning, while Mikoto is getting ready to meet her friend Sane, something strange yet familiar appears in her bedroom. It's another version of herself, which came straight out of her dreams! Now Mikoto and Sane can teach dream-Mikoto all about the wonders of the real world as they enjoy their time together. However, when dream-Mikoto crossed into reality, she left an opening behind her that other dream creatures could cross as well. Will they be able to block the passageway before something unfortunate happens?
