Honkai: Star Rail: Dr. Ratio Acrylic Keychain - Boys' Dormitory Series [1634]

Even the most brilliant minds in the Intelligentsia Guild need some downtime. We've seen Dr. Ratio throw chalk and hand out failing grades, but seeing him in this cozy owl Absolutely logical. This is the side of the Doctor that the most dedicated Trailblazers get to see.

Visual Highlights

This keychain captures Dr. Ratio in a rare, relaxed moment. He's wearing an adorable owl-themed hoodie while clutching his favorite book, and yes—there's a tiny yellow duck sitting right on top of his head! It's a perfect nod to his iconic bath-time idle animation. The set comes with a premium lavender woven strap and a super soft purple pom-pom that adds a cozy, tactile feel to your bag or keys.

For Collectors

Part of the 'Boys' Dormitory' series, this piece is a must-have for Dr. Ratio fans who appreciate the gap between his stern academic persona and his surprisingly cute casual side. It even features a smaller dangling charm of a sleepy owl at the bottom!
