Both series shares an amount quantity of elements. They are "shonen series", that means: young girls from highschool fighting between them with high level martial arts and superpowers, and losing their dresses in combat.

Is difficult to find in any of them a scene without close ups boobs or underwear or some kind of (barely explicit) sexualy sugesttive material.

Though with a ghost named Misao following him around, Tomoharu is far from being an average teenager. One day a strange woman appears and gives him a trunk that contains a tremendous power. This power is known as an Asura Machina - a being that draws its strength from a human sacrifice - and the sacrifice within Tomoharu's Asura is none other than Misao. As the bearer of such a power, Tomoharu immediately becomes the target of various groups, including the Divine Guards, who want his power for their own. When Tomoharu befriends a demon called Kanade and she is captured by the Divine Guards, he joins the Dark Society in order to save her. Now, Tomoharu will have to fight alongside the Dark Society while he tries to find a way to save Misao and bring her back to life.
Each series focuses around a character getting drawn into a magical world and finding out they are a rather important part of the world. Futhermore, there is a rather complex gambit going on in the background. Finally, each series is rather ecchi (although Qwaser is much more so).
