After Akiko tells Shotaro of how she stayed up all night watching a jidaigeki DVD box set, a sleep deprived young woman comes in claiming she is unable to sleep because of a monster that has invaded her dreams like six other college students. Akiko deduces that it must be a Dopant, a fact that Philip goes to investigate out of interest. After introducing herself as Himeka Yukimura and claiming Shotaro to be her destined "prince", she brings him and Akiko to Futo University where she is part of a lucid dream sleep study led by absent-minded Professor Akagi and his aid Hajime Fukushima.
