Sega has unveiled a new collaboration for Hatsune Miku: Colorful Stage featuring costumes designed by Vtuber Ironmouse. These outfits, created by artists epebe and Rosuuri, are being introduced to the mobile title as part of a Halloween-themed event.
Players can obtain a Mousey Avatar Full Costume and a custom profile illustration by Rosuuri through a Halloween Special Login Campaign. This promotional event remains active until November 6, 2026, and guarantees at least one costume change for participants.
Additional designs are accessible via the Premium Gift Gacha, which requires 3,000 Paid Crystals per pull. This purchase unlocks male and female versions of the attire for all characters, offering the original pink and purple palette alongside three alternative color variations.
The crossover content is currently available on Android and iOS devices through November 6, 2026. While the game features these new cosmetic items and a teaser trailer, there has been no official announcement regarding the inclusion of Ironmouse songs.
