第 12 集: 輝夜大小姐想告白~天才們的戀愛頭腦戰~ 告白實行篇 第2話 / 第3話 / 雙向告白篇 第1話

Ai urges Kaguya to do everything she has longed to do to Miyuki before he leaves, for which she devises a plan that, after lighting up a campfire with a bow and arrow as a part of the festival, Kaguya would confess to him while drinking canned coffee. While they search for Miyuki, Yu learns at a theatre he had confessed to Tsubame. Without success of finding him, Kaguya sets the wood structure on fire but then a phantom thief Arsène mysteriously drops several cryptic messages written on paper on the crowd watching. Chika invites Kaguya to solve the riddle game but Kaguya believes it is just a red herring and goes directly to the spot those papers were dropped.
