Honkai: Star Rail: Dr. Ratio Acrylic Keychain - Boys' Dormitory Series [1614]

Zero points! Or perhaps... a perfect score for cuteness? We're used to Dr. Ratio lecturing us on logic and mathematics, but the Boys' Dormitory series gives us a rare glimpse into the Intelligentsia Guild's most brilliant (and eccentric) scholar during his off-hours. Even a genius needs a moment to relax, right?

Visual Highlights

This isn't your average keychain. It features an adorable chibi Veritas Ratio looking surprisingly cozy with a fluffy towel and his signature rubber ducky—a nod to the bathtub memes we all know and love. The art style is soft and charming, perfectly capturing his 'done with everyone' expression in the cutest way possible. It even comes with a unique, color-coordinated beaded strap and a secondary mini-charm of his iconic marble head!

For Collectors

Part of the 'Boys' Dormitory' collection, this piece is a must-have for anyone who's spent their Stellar Jades (or luck) on the doctor. It looks fantastic hanging from a bag or displayed alongside other HSR acrylics to create a little slice of the Astral Express dormitory on your shelf.
