Demon Slayer: Koyuki Tsumamare Rubber Keychain - Infinity Castle Arc

If you're still not over the heartbreaking backstory of Hakuji and Koyuki from the Infinity Castle arc, you're not alone. This adorable keychain captures Koyuki in COSPA's signature 'Tsumamare' style, looking like she's being gently picked up by her collar. It’s a sweet, soft reminder of of the most emotional relationships in the series.

Visual Highlights

The detail on this rubber strap is precious—they've perfectly captured Koyuki's iconic flower-shaped pupils and her gentle, smiling expression. She's wearing her signature pink polka-dot kimono with the light blue floral trim, complete with her yellow comb and blue flower hairpins. The 'pinched' pose makes it look like she's dangling right from your bag or keys!

For Collectors

COSPA's Tsumamare series is a fan-favorite for a reason. The soft PVC material is durable and the design is uniquely charming. Whether you're a dedicated collector of the Upper Moon backstories or just want to keep a piece of Koyuki's kindness with you, this is a must-have piece for your Demon Slayer display.
