Since Volume 19 is going to be out, here comes speculation time. Topic of speculation: KUNOU! Why has Kunou went to Kuoh Town?

My idea, she went there with her mother and a few young Youkais who will be first years in Kuoh Academy. As part of the peace treaty alliance or whatever name it is, other factions sent out a few of their young warriors to Kuoh Academy to try and support DxD.
