If you are the only male in all girl school what would you expect? Harem ofcourse. This is a story about the only male spirit contractor Kazehaya Kamito in all girl school where he was forced to atend by his old acuintance Greyworth the principal of the school. Because of the upcoming festival Blade Dance he was unwillingly participate to competete in the festival and beat Ren Ashbell in exchange of information about Restia the spirit that he search. The story is your average boys meet girls at first but it was develope into something better but still cliche. What Atract me the most is the cast so lets give a little brief about them.

Kazehaya Kamito
The MC of this series and the only male spirit contractor. Most of people warry of him since in the past Demon King that is the only male spirit contractor create chaos. But because of his ever growing harem now he have a tittle himself that is Demon King of the Night. He is on a quest for searching his past contracted spirit Restia.

Claire Rogue
Our female heroine is red haired pettanko twin tail tsundere. Her affinity is fire and her spirit is a cat. She often revered as Hellcat Ojou-sama. Even thought she is smart she is always causing problem that make her enemy of Sylphid Knight the school police. Despite that she is a good leader.

Rinslet Laurenfrost
She is Claire rival and her childhood friend. Despite always bickering they are stay a good friend not that either of them would admit it. Her affinity is ice so that it natural that she and Claire is rival. She have maid but for some reason it was her that have household skill whereas the maid is useless.

Ellis Fahrengard
Captain of Sylphid Knight and overall strict person. She was not in good term with Claire because she always cause problem. Her affinity is wind. Her skill on cooking is good but still not on level of Rinslet. She say that she practice cooking for pleasing her future husband. Even thought she is strict she have soft spot on cute thing.

Fianna Ray Odesia
She is the seductive type person. Her first appearance is in volume 2. She meet Kamito few years before the story begin but he doesn't remember her. Since she is princess maiden in combat she is act as a support. Claire sometimes refer her as immodest princest due to the fact that she always seduce Kamito.

Est
Kamito sword spirit and my personal favorite. She is a high level spirit since she can appeare in human form. Sometimes reffered as naked kneesock spirit because she often sneak into Kamito bed wearing nothing but stocking since for some reason she thought that showing her feet is embarsing. She is very loyal to Kamito. Revered by author as Unmovable Queen due to the fact that she nearly always in top popularity poll.

Restia
Mysterious darkness spirit that Kamito searching. She was Kamito contracted spirit in the past.
