A Project Where Fan Support Lights Up the City
The “Untitled x HBC Birthday Project 2026” is designed to create a shared celebration between members, fans, and HBC. At its core, the project empowers fans to directly influence the scale of birthday promotions for “Untitled” members. By participating in the creation and purchase of exclusive birthday merchandise, fans can increase the visibility of their beloved idols across HBC’s various media platforms. This includes digital signage at the HBC headquarters, dedicated segments on HBC television programs, and special announcements on HBC radio shows.
The journey begins with the fans’ direct input. During live streams on the “Untitled no Pakirasshu★” Pococha account, members will unveil design proposals for birthday goods. Viewers will then join in to help select the final designs, ensuring that the merchandise truly reflects the collective spirit of the celebration. It’s a unique opportunity to shape the very items that commemorate these special occasions.
The level of public celebration scales with fan engagement:
-
1-49 items sold: Exclusive birthday goods only.
-
50-99 items sold: Goods plus a projection on HBC’s corporate signage.
-
100-149 items sold: Goods, signage projection, and a 1-minute slot on HBC Radio.
-
150-199 items sold: Goods, signage projection, a 3-minute slot on HBC Radio, and a 1-minute segment on HBC TV.
-
200 items sold: Goods, signage projection, a 3-minute slot on HBC Radio, and a 3-minute segment on HBC TV.
Imagine the thrill of seeing your name, as a purchaser, scroll across a prominent digital display, knowing your support directly contributed to your idol’s special day. This direct correlation between fan action and public recognition is a powerful testament to the project’s innovative approach.
