Kazuma is from the Kannagi family – a family of fire users. He’s the one person in the whole family that can’t use fire. As a child one of his distant relatives, Ayano, beat him in a dual because of his inability to use fire and his father banished him from the family – never to be allowed to return because of the disgrace. While out surviving on his own he forms a contract with the wind spirit to become a wind user. Because his power to control wind comes from the spirit itself his power is beyond that of other users.

Returning home he finds his family still refuses to let him be a part of the family, and that is just fine by him as he doesn’t want anything to do with his family either. His relative Ayano has become the one who will inherit the families sword, Enraiha. Unfortunately she isn’t yet up to the task and needs help. And that help seems to keep coming from Kazuma, whom Ayano finds to be one of the most annoying jerks she has ever met. That coupled with the fact the family considers him a traitor makes for some tense situations. Those tense situations become even more fired up when Ayano begins to have feelings for the fire-wielding Kazuma.

Kazuma just wants the money that comes along with helping Ayano perform the tasks set before her that come with wielding Enraiha. Time and time-again Kazuma ends up coming to her rescue and helping her out just enough to keep her from losing. The situation gets complicated when members of the Kannagi family start mysteriously dying – and the evidence points to a wind user. Can Ayano overcome her mixed feelings for Kazuma and trust in him or will she draw her sword against her new friend?
