The Happidanbui “Munyu Gurumi Patio” collaboration starts September 23!

A pop-up store featuring Sanrio’s six-member boy group “Hapidanbui” will be held in collaboration with “Munyu Gurumi Patio,” operated by KThingS.
The event will run from Wednesday, September 23, 2026 (a national holiday) through Tuesday, October 6. The venue is AKIBA LINK on the 1st floor of Ecute Akihabara, a shopping complex located inside JR Akihabara Station.

In the released visuals, the six members of Hapidanbui are transformed into angels and little devils. The illustrations distinguish between their appearances—one featuring fluffy wings and the other adorned with bat-like wings and horns—and, combined with a background scattered with pale pink and gray hearts, create a soft color scheme.
