Upon receiving an invitation to a treasure hunt from the famous mysterious item artist Reinette, Ramune and Kuro visit Reinette's mansion. There they encounter Ayame and Nico, who have also come to participate in the treasure hunt. However, when Ramune sees the man with them, his expression freezes, and he attempts to flee the scene. That man is Ramune's master Momiji!
The object Reinette held on to until the end.
.الشّيء الّذي تمسّك به رينيت حتّى النّهاية
Der Gegenstand, den Reinette
bis zum Ende in seiner Hand hielt,
El objeto que Reinette
sostuvo hasta el final.
Une chose qu’il a tenue
jusqu’à sa mort…
L'oggetto che Reinette 
ha impugnato fino alla morte.
O objeto que o Reinette
não largou até morrer.
Предмет, что Рейнетт держал в руках
до самой смерти.
