Mika was adopted at the age of two. His human and her mother, while volunteering, decided to bring him home “just for a little while.” But the moment he walked through the door, Mika settled in as if he had always belonged there. That very same afternoon, they knew they could never let him go: he had found his true home. It is said that his previous owner was an elderly man who had passed away.

He's a little short-legged plush cow. Very relaxed and calm, and even more so with age; he strolls slowly, sniffing everything around him. He loves cuddles: he jumps on you whether you're sitting or lying down, and if you stop petting him, he uses his eyes, movements, or tongue to ask for more. He makes little happy sounds, lies on his side anywhere, and to get attention, rolls over onto his back like a little croquette.
He can be possessive with toys or bones, hiding them like a clever little fox. He loves to eat, is rounder than he should be, and adores having his backside scratched.
He's very vocal when he wants attention and has a spot on his side that looks like Mickey Mouse.

He has a protective attitude toward his fellow canine adventurers, having especially defended Kei, and joins in when the others react to something. He's like a father figure to Chany: when Chany was smaller, Mika let him play and get away with everything. On walks, he uses his nose to show Chany where to dig and watches with his tail wagging as Chany excavates.

Easily influenced by his companions; joins in barking without knowing why.
Extremely lazy; wags his tail and watches, but doesn't come for attention.
Treats every toy as a challenge to see how long it takes to destroy it.
Jealous; if you pet another dog, he has to join in.
