Kidthlete

Kidthletes are a sapient species of anime-styled preteen children (8 to 13 years old) that don't age permanently, and are only wearing basketball shorts with compression shorts or cycling shorts underneath their shorts, socks and football cleats. While boys are shirtless, girls wear zipper sports bras with bikini bras underneath their zipper sports bras.

They have non-Japanese first names with Japanese last names as well. They are so cute that they don't become teenagers in the following years.

They are extremely peaceful and gentle towards all sapient species and sapient beings, except vampires due to bloody conflicts with them. They are omnivores that feed on the same kind of food as many other sapient species and sapient beings.
