Dream: Loving Each Other

In an insane effort to reform their anti-social housemate, the boys decide to redecorate, and just in time for Josephine's wedding . . . After realizing that she just doesn't look like she fits in anymore, Sunako-chan does the unthinkable: she puts on a dress!  But on a regular grocery shopping trip, she is singled out for her odd goth attire (including black veil) and is mistaken for a kidnapper when a local child offers to take her to his hideout, where she will be safe from the townsfolk.  When Noi-chi sees Sunako-chan on television, she devises a plan to rescue the 'princess': a plan that involves Kyouhei, a white steed, and . . . cosplay . . .?
