Omamori Himari, Volume 7

Forced to stand by and watch as Himari faces off against an onslaught of monsters ordered to attack by Tamamo-no-mae, Yuuto finally accepts his role as a demon slayer! But acceptance doesn't automatically make him good at it, and the young warrior must continue training to become master of his own potential! And during one such training session, Yuuto runs into another sleuth-like slayer, Hitsugi Yakouin! Will Yuuto learn a thing or two about using his own Light Ferry powers with her?
