Hidan no Aria is a light novel series written by Chuugaku Akamatsu with illustrations from Kobuichi. The series began in Media Factory’s MF Bunko J in August 2008. To date there are 16 volumes with the 17th volume releasing on the 28th, and the series has sold over 2 million copies. A manga adaptation began serialization in 2009 by Yoshino Koyoka. A anime adaptation aired from April 2011 till June that year, and was animated by J.C.Staff. An OVA followed the series in December 2011.
Here is a synopsis from MAL:
Kinji is a junior at a high school for mercenaries. He just wants to be normal, but his secret condition—he turns into an ace killer when he’s turned on by the female form—triggers a fiery transfer student’s unrelenting desire to make him her partner.
The new Hidan no Aria project, whether it is a new light novel, or anime, will be announced next season.
