Kira was always a lonely wolf. He doesn't really need others. When Tala found him and gave him a chance, he wasn't very sure about it. But as he's pack started to grow, a warm feeling appeared in his chest. He still does things on his own but now he has somewhere and someone to get back to. Because of his unreachable personality as a leader he resigned from being a breeding male after fullfiling his duty to have kids.
He has the most respect for Tobby, as he's older and more experienced than him. Kayle was the first member of his pack. They bonded well from the very start so they became mates. Kira trusts her with his life and he knows that she will be capable of taking care of the pack when he's gone, although he's not really sure if this is true love. He's hopeless at feelings.
