This is a new work which I've been touching on these past few weeks. High School DxD EX is basically a spin-off of High School DxD Light Novel/Manga series, focusing on the children of the main protagonist Hyoudou Issei with his harem of main characters. They come from the future in a time-travel fashion (with a supernatural premise instead of the normal science-fiction gizmo) to stop a well-known enemy along with his extraterrestrial army from messing up with the timeline.
In an otaku's term, the plot is basically based off Boruto with the Spin-offspring base characters in a Chrono Trigger or X-Men: Days of Future Past time-travel setting with some Gundam and Super Sentai thrown in. No, really, you will find more of these aspects when you dwell more into the story as you read. While the typical time-travel problems appear, such as nobody will die, time paradox, your stereotype time-bending villain, and multiple timelines with shades of over-powered future characters (which is a requirement for their mission), the EX series spices it up a bit by adding foreshadowing to the main series instead of being an independent story entirely (it was set in the middle of the novel's continuation, after all) because of the changes in the anime (this also marks as one of the few franchise I know to weld its different forms of media into a single alternate narrative, yet still connected to the main series Japanese-style instead of making each other independent, as Western popular comic books can attest).
There are six chapters in total, since basically it is exclusively bundled with the third season anime, BorN (the timeline it tied to), DVD and Blu-Ray to fill the gap between the volumes 20 to 21 (along with the DX2 compilation).
Because it is still on-going, this post will be updated as I worked with the translation by giving the links to the full text of each chapters.
I will wait for the first three chapters to be translated by other translator, by the way.
Do note that the posts in here are carbon copy/reposts to the summaries I posted in Animesuki forums, so the narration and dialogues are a bit jarring. The final version submitted to Baka-Tsuki will be a bit different, with fixes in names and all that entails.
Chapter 4: Crimson Will
Chapter 5: The Forbidden United Front
Chapter 6: And so, to Tomorrow...
