Pkpk, also known as Pikupiku, is one of the three main fairy characters in the anime gdgd Fairies. She lives in the Fairy Forest together with her two companions, Korokoro and Shirushiru, and is presented as a young female fairy with a childlike appearance, pink eyes, and pink hair that reaches her neck.

Her personality is depicted as mild and innocuous, and she tends to be somewhat timid when interacting with others. This gentle, cautious temperament contrasts with the livelier behavior of her friends and contributes to the group's comedic dynamic during their everyday activities.

Within the story, Pkpk is a core member of the three-fairy ensemble rather than a solitary protagonist. The trio spends time in casual conversation, practices magic in a special room where their magical power is amplified, and watches scenes of the outside world in a fountain, often improvising dialogue as they go. The fairies are generally weak in magic skill, and Pkpk shares that modest level of ability; the magic room mostly serves as a place where they can play with spells and summon objects for amusement rather than a setting for serious magical feats.

Her key relationships are with her fellow fairies, with whom she shares almost all of her screen time. The interaction between the three personalities drives much of the series' humor, and Pkpk often serves as the quieter member of the group in these exchanges. A character song associated with her is titled Pink Pixie, reflecting the pink theme of her design.

Because gdgd Fairies is an episodic comedy built on rambling conversations, improvised skits, and surreal situations, Pkpk does not undergo a pronounced character arc across the series. Her development is limited, and she remains a consistently shy and gentle fairy whose identity is defined mainly by her place within the trio and her participation in the recurring games and routines of the Fairy Forest.
