Demon Lord Retry anime
Released in English 11 days ago, my copy arrived Friday. Just finished binge watching it, and I'd rate it as a good representation of the story up through the beginning of the Akira's trip north. There were things left out - like the uncertainty of Aku's sex at the start - but it covered a heck of a lot more "major plot points" than the Smartphone anime did.
I hope a second season is coming, even though Funimation is billing it as "The Complete Series!"
