Name: Kei Calico Nuko (Male) Personality: Kind but tsundere Height: Approx. 24cm Weight: Just under 1kg Likes: Sashimi, miso soup (Yuya's homemade) Favorite Spot: On top of the beanbag chair Since male calico cats are rare and Sasame is a "tomboyish female," he ended up as a "pretty-faced, shy male." Lately, he's been worried about not being able to act like a big brother. He helps Yuya cook and do chores. He is a Nuko kept by Yuya and lives with him. He often yells at Yuya, saying, "You're the owner, so get your act together!" He can't drink alcohol and gets drunk just from the smell.

Name: Sasame Black Nuko (Female) Personality: Kind, fluffy/airy Height: Approx. 23cm Weight: 800g Likes: Salt-grilled fish, cocoa Favorite Spot: On top of Yuya's head (apparently it's fluffy and feels good) Since she's still a kitten, she mostly just mimics her senior, Kei, but lately, her own sense of self seems to be establishing... despite her appearance, she has a rather gallant personality. She is a Nuko kept by Yuya and lives with him. She doesn't drink, but gets drunk from the smell.
