As punishment for the underwear incident, Mizuto demands Yume go on a date with him. Yume is taken aback by the sudden development, but little did she know that it was all part of Kawanami Kogure's devious plan, a plan to shatter Minami Akatsuki's delusional dreams of marrying Mizuto only to become Yume's doting little sister. And how else to do it but to show her that Yume only has eyes for Mizuto?
Should we move this date to a mental
 institution, Miss Mystery Buff?
أعتقد أنّ عليك الذّهاب لمصحّة
.نفسيّة أيّتها المهووسة بالغموض
Dich sollte man wohl besser einweisen
mit deiner Krimisucht.
Necesitas ayuda psicológica,
señorita misterio.
Necesitas ayuda psicológica,

Je te conseille
d’aller te faire soigner.
Credo che qualcuno dovrebbe farsi curare,
signorina fissata col mistero.
Talvez alguém precise ir para
um manicômio, Srta. do Mistério.
Кому-то пора в психбольницу,
любительница тайн.
