The series' power system is based on magic and game pieces, such as Evil Pieces (chess pieces) and Brave Saints (set of cards). This was done at such a great extent that Ishibumi created such a unique, intricate, and immersive world to study and explore, something you rarely see in most harem and ecchi series. The story takes aspects of religion ranging from Buddhism to Christian, Hindu, Norse, Greek, Japanese, Irish, Chinese, Egyptian, Celtic, and Persian mythologies, and incorporates them into the characters, world building, power structuring, race & identity, history, and politics in the DxD universe. And given that the story is told in first person, we get to read Issei's thoughts and opinions on whatever scenario he's in, which provides us a lot of the comedy and important information that is presented throughout the series and not often translated into the anime. This can be put to good use as Issei is not always at the centre of attention, as the story can switch over to a completely different set of characters that can give context to certain events throughout the story.

The story is told from the perspective of the character in focus, as it's primarily from Issei's POV, but the story can also switch over to other characters like Kiba, Rias or Azazel. Issei wakes up lying next to her naked, revealing herself to be a devil and thus begins Issei's journey as a devil and a pawn of Rias Gremory from the Gremory household. Before he died, a crimson red beauty appeared before him and resurrected him.

It turned out that Issei's 'girlfriend' happened to be a Fallen Angel on a mission with Issei in her crosshairs. This series entails the rise of our perverted protagonist as he unfortunately gets murdered by his very first girlfriend as they’re about to finish their first date. This is a story about growth and a journey toward one's goals, or more specifically, the growth of Issei Hyoudou, our main protagonist of the story.

I love the anime, and I decided that it would be best to start reading ahead in the novels in preparation of the fifth season little did I know that picking up the novels was probably the best decision I've made all year. High School DxD is a staple within the anime community, becoming one of the most popular ecchi series of all time thanks to its raunchy ecchi, well-crafted English dub, funny cast of characters, and its story telling. A powerful quote from a monstrously powerful idiot. 'Stupidity is fine! If I can't win with ability, I'll excel through stupidity!' - Issei Hyoudou.
