Like the other main kittens, he has pink star-shaped paw pads and a yellow star in his left ear.
Peko loves eating. He also likes to make everyone laugh. He speaks Kansai dialect.
Maira Tsukishima: Maira is Peko's partner. They have the same interest in comedy, and make a comedy duo named "Dasshi♡Fun'nyuu" (だっし♡ふんにゅう; lit. "skim milk powder").
