The moment the culture festival reached its finale, the jewel object made by Shirogane was stolen by a phantom thief who calls himself Arsène. Kaguya and the others headed to the roof where the phantom thief keeps appearing, but there was no one there. Fujiwara, who transformed into a genius detective, struggles to solve the mystery behind the calling card and uncover the thief's true identity. But Kaguya, left behind at the scene of the crime, had begun to figure out the criminal. The problem is the location. Kaguya traced the phantom thief's line of thinking and headed to where he is now...
It's like I blatantly threw myself at her,
and now I'm so mortified!
!وكأني رميت بنفسي إليها علنًا، والآن أنا محرج للغاية
Ich hab ihr unbeabsichtigt vor allen
den Hof gemacht! Wie peinlich!
Le declaré mi amor abiertamente.
Le he declarado mi amor abiertamente.
J’ai montré mon amour sans détour,
c’est embarrassant.
Le ho praticamente detto che mi piace
 davanti a tutti, che vergogna!
Declarei meu amor abertamente.
Agora fiquei com envergonhado.
И стыдно! Она-то решила,
что я смело признался у всех на виду!
