Honkai: Star Rail: Sunday Acrylic Keychain - Boys' Dormitory Series [3179]

Our favorite head of the Oak Family is looking a lot more relaxed than usual! The Boys' Dormitory series gives us a rare glimpse of Sunday in a softer, cozy aesthetic. If you're still processing the Penacony arc, this little charm is exactly the healing we all need.

Visual Highlights

This isn't just a standard acrylic stand—it comes with a beautiful coordinated beaded strap in soft blue and yellow tones that matches Sunday's palette perfectly. The chibi art captures his signature halo and those delicate wings behind his ears, all while he wears a more casual dormitory-style outfit. There's even a tiny secondary charm of his face attached to the ring for double the cuteness!

For Collectors

The Boys' Dormitory series is a must-have for those who love seeing the Astral Express and Penacony cast in everyday settings. It's the perfect size for your keys, bag, or even as a small decorative accent for your PC setup.
