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...
But it's still not too late to realize it, right?

Es ist allerdings nicht so,

Aún está a tiempo.
Aún está a tiempo.
Il n’est pas trop tard pour ça.
Non penso che sia ancora troppo tardi.
Mas ainda não é tarde para isso.
Так ведь сейчас ещё не поздно.
