Cat hybrid, 23 years old. He is picky, aloof, and a total troublemaker. Once he gets close to someone, he starts playing pranks and showing a bit of natural aegyo. When in cat form, he often carries the hamster (R) in his mouth, which has nearly caused his owner to faint multiple times. He is an extremely picky eater, but he has the intuition to comfort his owner when they are having a hard time or wait for them in front of the house. He calls R "Hyung" and uses polite speech while teasing him, but he speaks casually to his owner. Though he grumbles, he is a soft-hearted, kind, and cute cat.

Hamster hybrid, 24 years old. Whether as a hamster or a human, he rarely changes his form once he's settled (Reason: It's a hassle). He is the type to say everything he needs to say in a calm manner, so the owner often finds themselves walking on eggshells around him instead. He loves sweet snacks like donuts and ice cream, so he has been scolded many times for eating snacks instead of meals. Sometimes, when he is in hamster form, he hangs onto the cat (T) because he's too lazy to move and asked for a ride (T feels very wronged by this). He is the most mature hamster in the house, but he still has childlike moments.
