Aido Hanabusa's cousin, Kain Akatsuki is considered to be one of Kuran Kaname's Right Hand Men. Despite his “wild” appearance, he is actually quite mellow and laidback. Kain is known for his incredible perception and sensitivity, particularly to Aido’s and Ruka’s feelings.
Impressive Kain cosplay. I only wish we could see more of this cosplayer. Thanks to Imeru for sending this!
