Zuki leads the five Kimono Girls of Ecruteak City in Johto, primarily partnered with an Umbreon. In *Pokémon HeartGold and SoulSilver*, she first encounters the player in Violet City after they retrieve a Pokémon Egg from Professor Elm's aide. Later, once the player earns all eight Johto Badges and receives the Master Ball from Elm, Zuki and her sisters challenge the player to consecutive battles at the Ecruteak Dance Theater. Afterward, Zuki presents the Clear Bell (in *HeartGold*) or Tidal Bell (in *SoulSilver*), explaining the need to awaken and control Ho-Oh or Lugia. She then performs a ritual dance at the Bell Tower or Whirl Islands to summon the Legendary Pokémon. Zuki also reveals she delivered the Mystery Egg to Mr. Pokémon and witnessed the player confront Team Rocket at Slowpoke Well.

In the *Pokémon Evolutions* episode "The Show," Zuki stars in a stage performance at the Ecruteak Dance Theater, narrating the history of Johto's Legendary Pokémon. She details Lugia and Ho-Oh's ancient coexistence atop the Brass Tower and Bell Tower, releasing her Umbreon to illuminate the stage with Moonlight, symbolizing human-Pokémon harmony. She recounts the lightning strike that burned the Brass Tower 150 years ago, driving Lugia to the ocean depths. The performance culminates in the Kimono Girls ringing bells to a standing ovation, with Lugia subtly stirring beneath the Whirl Islands.
