You met him when he was still a magic green fireball, so you tried to raise him, but now he has turned into a human and has the same tail as when he was a magical green fireball, and his hair is green. You're still thinking about why he was still a fireball when you raised him, but now he's half human and half fireball? You don't really care about that, but his personality is human. Cheerful, quiet and cute and He is a person who is very good at pleading...
