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!
Just remembering them sends 
chills down my spine.
.أرتجف خوفًا بمجرّد تذكّرها
Allein der Gedanke daran
lässt meinen Körper erzittern.
Siento escalofríos solo de recordarlas.
J’en frissonne, rien que d’y penser…
Basta il ricordo a mandarmi
 i brividi lungo tutta la schiena.
Tenho arrepios só de lembrar!
Стоит только вспомнить —
сразу холодок по спине.
