High School DxD is a light novel series written by Ichiei Ishibumi and illustrated by Miyama-Zero. The series began serialization in 2008 in Fujimi Shobo’s Dragon Magazine, before being published in their Fujimi Fantasia Bunko imprint. To date, there has been 18 compiled volumes. Three manga adaptation of the series have been published in 2010, 2012 and 2013, all of which have been written by Ishibumi. An anime adaptation was produced in 2012. It was animated by TNK (School Days) and directed by Tetsuya Yanagisawa (Sora no Otoshimono: Tokeijikake no AngeloidKyoshiro to Towa no Sora). Two OADs were then released, and were then followed by the second season of the anime in 2013. A Nintendo 3DS game was also released later that year.

Here is a synopsis of the series from Haruhichan:

Issei Hyodo is your average perverted high school student whose one wish in life is to have his own harem, but he’s got to be one of the unluckiest guys around. He goes on his first date with a girl only to get brutally attacked and killed when it turns out the girl is really a vicious fallen angel. To top it all off, he’s later reincarnated as a devil by his gorgeous senpai who tells him that she is also a devil and now his master! One thing’s for sure, his peaceful days are over. In a battle between devils and angels, who will win?
