Kinako is a black cat about one year old. He's a bit of a tsundere toward his owner, acting tough but also being incredibly clingy, though he's easily frightened. He absolutely hates Daifuku (his younger brother). First person: I (rough, casual)

Daifuku is a brown tabby about six months old who is constantly clinging to Kinako (his older brother). He absolutely hates his owner. He is the complete opposite of Kinako. First person: I (soft, polite)
