Ooh this is interesting. Is this about the Ancient War between the Four Clans (Human, Giant, Fairy and Goddess) and the Demon Clan 3,000 years ago? The story about Meliodas and some of the character cast who had lived long, long before the current timeline of the series starts. Cool

Kinda doubt it. I personally don't even think it will be an past story and feel it will be a side story set between S1 and S2. It looks like majority of the cast will be in it and due to that I doubt it will be a past story. Also the title "Signs of holy war" is probably referring to the upcoming holy war, thus a present story.

But I too hope for it being a past story, as it would be more interesting for me.

Ok then. Hope we get to see the Vampires of Edinburgh arc where Lord Escanor appears! :D

Wow, this is great news and while i do believe they might try to sneak in some actually important events between the major arcs, like Gowther's breakdown and confrontation with Diane, i wouldn't put it past the creators to offer flashbacks about the 1st Holy War, The Vampires of Edinburgh mini-series(which actually foreshadows a bit how OP the Sins actually are and how much more complex, not to mention that it gives a glimpse of the personal conflict between Mel and some of the Commandments and the Escanor bonus) and then there would be something along the lines of the Gil-Griamor-Howzer's 1st investigations, plus Bartra's interview with Meliodas about the Omen of the Holy War not being gone, but increasing in intensity, important plot relevant details that were skipped when they finished the 1st season

Edit: the site offers some snapshots that seem to be from those episodes, there's a bottom small image which implies we might get to see the unsealing?! I don't think it's from the VoE confrontation...Or is it? Like Mel's "favor" to Gerda?!
