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...
I'm going to sip some canned coffee
as I hand him a heart. That's all.
.سأحتسي قهوة معلّبة وأعطيه قلبًا. هذا كلّ شيء
Ich brauche ihm lediglich bei einer
Dose Kaffee mein Herz überreichen.
Le daré el corazón mientras
bebemos café enlatado.
Le daré el corazón mientras
bebemos café enlatado.
Je lui donnerai un cœur
avec une canette de café.
Mi limiterò a dargli un cuore
 mentre sorseggiamo un caffè.
Vou só entregar meu coração
enquanto tomo um cafezinho.
Я просто отдам сердце, 
глядя на костёр во дворе.
