TV Special
Description
Ky Schweitzer, alias Kai, holds the rank of Lieutenant General in the Black Gema Gema Gang, devoted to aiding their leader, Piyoko. Seventeen years old, he practices dentistry and constantly stresses dental hygiene, keeping a vigilant watch on Piyoko's tooth-brushing routine. Though he finds the title embarrassing, the gang's familial structure designates him as the "Mommy," a role requiring nurturing duties.

He possesses dark blue hair with purplish tones, purplish-red eyes, black dog ears, and a tail. His signature look includes glasses, a white doctor's uniform, a prominent black dog-collar necklace, a white leaf-shaped hair accessory, black pants, and brown sandals with red straps.

Ky typically exhibits a serious, gentle, and caring nature, prone to panic when situations unravel. He readily praises Piyoko but can become dominating and rude, especially towards fellow gang member Coo, when angered. He first appeared in the *Christmas Special* (2000), joining Rik and Coo to help Piyoko capture Dejiko during a cruise; the gang ultimately abandoned the scheme to celebrate Christmas peacefully with Dejiko's friends.

In later seasonal specials like *Ohanami Special* and *Natsuyasumi Special*, Ky remains the gang's meticulous and anxious caretaker. The group's interactions with Dejiko shift from antagonism to occasional cooperation, such as sharing picnics or staging plays together, indicating less malicious pursuits. Within the alternate continuity of *Di Gi Charat Nyo!*, Ky persists as a steadfast Black Gema Gema Gang member, consistently focusing on Piyoko's welfare and dental care, his core traits unchanged. Official media provides no significant backstory or character development beyond these established roles.
