When you think of long running anime shows you might think ones like Naruto, Bleach, Fairy Tail, DBZ, or Fate stay night. These shows are well known in the Otaku culture and rightly so. One of the shows that you might not think of is Highschool DxD. This ecchi demon and angel oppai anime is getting a third season. Get ready to add it to the list of long running anime. It might surprise many people that this anime which has so much fan service and oppai in it would get a second let alone a third season. Even with all the oppai and ecchi in the light novels and manga (and there is a Lot of it) the story is very well done and interesting, he battles are intense and the characters are developed well to where you really get to know them. If you have not read the light novels or manga you should pick them up and take a look you light like them. The anime is very worth watching even if it does border on softcore porn.
For those that have read the light novels the third season should cover volumes 5 and 6. They seem to do two volumes per season. I say this because the first season seemed to cover volumes 1 and 2 while the second season covered 3 and 4. There isn’t much more information about the new season that I have found but post below if you find more or would like my personal opinion of Highschool DxD. I have posted below the article I found with some information in it about the new season.
