UDTT announces second single 'VIPER' with summer 2026 comeback

UDTT (우당탕탕 소녀단) is coming back this summer with their second single album, VIPER.

The five-member group — Lisako, Han Chaehee, Gu Hanna, Woojung, and Kwon Yejin — unveiled the VIPER logo on June 22 via official SNS. Hot pink. Serif typeface. Straight and curved lines interlocking.

Their debut single was School Rush, which leaned into bright, high-energy territory. VIPER goes somewhere else entirely. The agency framed it as "a song that maximizes UDTT's confident and honest charm," with music and performance distinct from their previous activities.

"We have prepared a more distinct team color and energy to blow away the summer heat," the agency added. (Hot pink serif for a song called VIPER — the pivot is already working.)

No release date beyond summer 2026.
