A Dream Team-Up: “Break My Case” Meets Sanrio Characters

Tokyo, Japan – The mobile app “Break My Case” (BreMy), developed by coly Inc., has officially kicked off its highly anticipated first in-game collaboration event. Starting today, November 29, 2025, players can dive into a world where the stylish characters of BreMy interact with the timeless cuteness of Sanrio’s most iconic figures, including Hello Kitty, Kuromi, Pochacco, My Melody, Pompompurin, and Cinnamoroll.

This special event runs until December 17, 2025, at 15:59 JST, promising a vibrant blend of puzzle-solving and heartwarming narratives. It’s an unprecedented crossover that brings a fresh wave of charm to the realistic ADV and groove match puzzle game. Fans are already buzzing with excitement over this unique fusion.

Exclusive Collaboration Cards Unveiled

The event introduces a collection of exclusive collaboration cards, beautifully illustrating BreMy’s Aporia staff alongside their new Sanrio friends. These limited-edition cards capture delightful moments, from snack times with Hello Kitty to adventurous outings with Pochacco.

Players have the chance to obtain the SR Shido Kyouya card, featuring My Melody, simply by participating in the event’s activities. Other standout cards include:

“KAWAII” Cafe and Special Story Await

At the heart of the collaboration is a charming narrative where the Aporia staff decides to host a “KAWAII” cafe. Unexpectedly, Hello Kitty and her friends arrive, offering their expertise to guide the staff in understanding the essence of “Kawaii” – a term describing cuteness that is a cornerstone of Japanese pop culture. By engaging in groove match puzzles and collecting event points, players can unlock this unique, limited-time story, enjoying the heartwarming interactions between the two worlds.

Further enhancing the experience, players can gather materials through puzzles to craft special Sanrio Characters-themed menus within Aporia. These “recipe memos” might even unveil hidden episodes featuring the paired Aporia staff and Sanrio characters, adding a layer of personal connection to the culinary adventure.

Groove to Sanrio Tunes

Adding a rhythmic twist, the collaboration introduces an event-exclusive playlist featuring vocal songs from the Sanrio Characters themselves. Players can enjoy these catchy tunes while tackling groove match puzzles:

Kuromi: “Greedy Greedy”
Cinnamoroll: “Kimi no Koto, Daidaisuki da mon☆”
Pompompurin: “Purin to Muffin no Pompom Beat☆”

It’s important to note that these songs will not be added to the regular playlist once the event concludes, making this a truly special, limited-time auditory treat.
