The Idolmaster: School Idols x Atre Akihabara Collaboration Event Announced

Get ready, producers! "The Idolmaster: School Idols" (Gakumasu) is collaborating with Atre Akihabara for a special event, "The Idolmaster: School Idols x Atre Akihabara," starting May 15, 2026.

The highlight of this collaboration is the brand-new "Early Summer" themed illustrations, featuring idols in their school uniforms enjoying themselves by the seaside. The entire Atre Akihabara building will be decorated with these vibrant visuals, transforming the area into a "Gakumasu" wonderland.

A wide array of original merchandise featuring these new illustrations will be available at the event space on the 2nd floor of Atre Akihabara 1. Look forward to acrylic stands, can badges, keyholders, and more, including new "Painter Style" illustrations featuring Tsubasa Amaya.

Please note that entry for May 15th to 17th will be by advance reservation. More details will be announced on the official "The Idolmaster" Official Shop website and their official X (formerly Twitter) account.
