Blue Archive: Arona & Prana Frame Square Bottle - Yostar 5th Anniversary

Can we just talk about how precious our OS daughters look together? To celebrate the Yostar 5th Anniversary, Arona and Prana are sharing the spotlight on this incredibly sleek frame square bottle. If you've been managing Schale since day seeing these two together like this just feels right.

Visual Highlights

This isn't your average water bottle—the "Frame Square" design makes it look like a portable piece of art. The illustration features Arona and Prana in a vibrant, celebratory style that perfectly captures their bond. Its slim, book-like profile means it slides perfectly into your bag alongside your tablet or notebooks without taking up awkward space. It's functional, aesthetic, and a total flex for any Sensei.
