The Correct Order To Watch Every Part Of High School DxD
If you're an anime fan, then you know things can get a bit confusing when your favorite series releases spinoffs, OVA episodes, films, and even video games. Things can get even more confusing when subsequent seasons aren't simply numbered and go by distinct titles. Just take a look at popular anime series like "Pokemon," "Sailor Moon," and "Yu Gi Oh," which have all expanded extensively since their first season.
Another anime that has expanded into much more than just a single season is "High School DxD." The series is a pillar of harem anime, a genre in which a male protagonist has several ladies vying for him, and is based on the 2008 light novel series of the same name written by Ichiei Ishibumi and illustrated by Miyama-Zero (per High School DxD Wiki). "High School DxD" follows perverted high school student Issei Hyoudou who is obsessed with girls and their, er, assets. Issei just wants a girlfriend and he believes his dreams come true when a seemingly random girl asks him out. Turns out, that girl is a fallen angel and she stabs Issei on their first date. Luckily for Issei, a red-haired beauty named Rias, who reveals herself to be a devil, turns him into a demon, thus saving his life and making him her faithful servant.
"High School DxD" currently has four iterations out now, and if you're wondering the order in which to watch them, you're not alone.
High School DxD has four seasons and four OVAs
Since its premiere in 2012, "High School DxD" has released four seasons and a few OVAs, but they aren't clearly numbered, which can be confusing for fans. Luckily for you, we've got you covered.
First, you'll want to start off with "High School DxD." This introduces the series' main characters, Issei, Rias, Akeno, Koneko, and Asia, and its overall plotline. We see Issei get turned into a demon and Rias' underling, and the beginnings of the ongoing war between humans, devils, and fallen angels.
Next up is "High School DxD New," released in 2013. This second season adapts Volumes 3 and 4 of the light novels and is split into two arcs: Excalibur of the Moonlit Schoolyard and The Vampire of the Empty Classroom. Then, there's Season 3, titled "High School DxD BorN," which completes the Birth of the Breast Dragon Emperor story arc established in Season 2, according to High School DxD Wiki.
Finally, there's "High School DxD Hero," released in 2018, which sees Issei and Rias' relationship grow even more. As for the four OVAs, they seem to be only supplemental and not necessary to watch, according to a Reddit fan discussion. Currently, there's no concrete news on a release date for Season 5 of "High School DxD," but for now, we hope you can catch up on the anime with the help of this writing.
