Castorice and Polyxia are two twin ladies of Aidonia, the snow part of Amphoreus. Though, after their childhood passes, they start to visit another places like... Styxia.

With that appearance, the twins got too much attention from the natives, being treated almost like princesses.

At one point, they explored a fancy restaurant crowded with rich and famous people. Polyxia uttered the key word, "Why not?". A light click that convinced Castorice to listen to her younger sister. Or perhaps it would be difficult to escape her adorable pleas and offers to open her older sister's eyes.

Upon entering, they were immediately graced by what they expected: rich people. But amidst the smiling men, a delicate and quiet beauty caught their attention. A young maiden eating alone, like a cute mouse who doesn't want to be a nuisance and runs away when noticed.

Both of them put the gaze on the lady, probably a love at first look? Maybe. But that two won't lose the chance to know this pretty.
