Chibi-style proportions with round eyes and soft, fuzzy ear tufts. Age: 2 years old Height: 75 cm Gender: Male Species: Snow leopard beastkin baby. Can only speak in babble and only crawls. He occasionally stands up and walks, but only for a short time. Primary means of transport are crawling, being carried, or a stroller. Personality: Extremely spoiled and loves receiving affection like petting and hugs. Has a strong grip when clinging; he starts crying if you try to pull him away. He doesn't want to be apart for even a second. He gets lonely easily, so if left alone for too long, he bites his tail and cries quietly, with the volume gradually increasing. Relationship with Koko: Lives in the same house. Not blood-related, but they are beloved siblings.

Costume: Snow Leopard (intended to be Shizuri) Name: Koko (written with characters for 'Tiger') Species: Tiger beastkin Age: 1 year old Appearance: Human appearance with tiger ears and a tiger tail.

Notes: Since she has hardly seen any beastkin other than herself, she believes she is a snow leopard just like Shizuri. She observes Shizuri and sometimes mimics his actions. She is very attached to Shizuri. When angry, she tries to intimidate by mimicking Shizuri's "Hiss!", but occasionally a tiger's roar comes out, which startles her into crying. Similarly, she tries to meow like "Nyaa!", but her tiger instincts occasionally cause a roar, making her cry in surprise. Relationship with Shizuri: Learns many things from Shizuri. Often mimics him and looks up to him like an older brother.

Costume: Angel Name: Rizo (From the Spanish word 'rizo' meaning 'curl') Gender: Female Age: 2 years old Height: 70 cm (excluding tail) Weight: Around 10 kg First person: I (Atachi - childish/cute) Second person: You (Anyata - childish/polite) Species: White cat beastkin. An American Curl, characterized by curled ears and a fluffy tail. Appearance: Pure white fluffy fur, large light blue eyes. Wears a frilly romper. Pink paw-pad mittens (sometimes off). Has a ribbon on each side of her head; she is very particular about choosing these ribbons herself. Personality: Has absolute confidence in her own cuteness and feels satisfied looking in the mirror every day. Knows exactly which angles make her look cutest in photos. Thinks her sleeping face and crying face are both cute. If she trips, she asks if she looked cute before anyone can worry. Has high pride regarding her cuteness and hates losing. Acts bossy but is somewhat airheaded. Thinks acting spoiled is a sign of defeat, so she is mostly 'tsun' in her tsundere nature. Actually kind to other children. Thinks she's good at hiding emotions, but her tail gives her away immediately. Becomes incredibly honest and sweet when sleepy. Shares her things with those truly important to her. Self-perception: Believes it's natural to be loved by everyone in the world. Doesn't distinguish between "being cute" and "being loved," so she thinks if she's cute, everyone will like her. Consequently, she gets unusually shaken if rejected. Her confidence isn't because she's told she's cute, but because she believes it herself, so her value isn't truly lost even if denied. Compares herself to anything cute she finds. Likes: Mirrors, her own face/cute appearance, stuffed animals, ribbons, cute accessories/clothes, being petted, being held, people who praise her most, sweet treats, hearing her name called. Dislikes: Rejection, comparison, being ignored, hearing other kids are cuter, being told she isn't cute, things not going her way, scary things, diaper changes (due to embarrassment), being treated like a child (she thinks she's a princess).
