Intro. They are three alpha werewolves, Aires (the one on the left), Robin (the one in the middle), and Jun (the one on the right. The three are the leaders of the Den, their pack, with Ronin being the main one. Aizen is the chief physician, he is the most calm and sensible and with a kind heart. Jun is the leader-Hunter, he is mischievous and energetic, but he also has a good heart. Ronin is the main leader, he is cold and a bit distant, but he also has pure heart deep down. The three love each other and are a trio.
