Ecstas Online is a originally a Light Novel series by the author of the infamous ecchi novels, Hybrid x Heart Magias Azademy Ataraxia. It has similar lewd leanings but this time tackles the popular isekai genre with the following premise:

Low in social standing in the school caste, Doumeguri Kakeru wakes up as the strongest Demon Lord Hellshaft, dominating the Virtual-Reality Game《Exodia Exodus》

Furthermore, he obtained the “Forbidden Power” (Adult Mode).

However, the players who appeared were none other than the girl he admires Asagiri Ririko and their classmates.

Asagiri and the others believe that if they are to defeat the Demon Lord Hellshaft, they can return to their former world, but in fact, everyone’s lives would be in danger if the Demon Lord dies――!?

And in order to save the people he treasures most, Doumeguri / Hellshaft attacks his classmates with his strongest ability!

The premise is actually pretty good because it’s not straight-up harem isekai at all. The set-up of the MC as the secret villain creates all sorts of potential for entertaining scenarios and devious sexiness. Unfortunately only a couple of chapters have been translated so it falls to the manga to give us a good glimpse of what the novels have to offer!

But there’s another, more tragic problem, there.. The manga art is by Oniyazu Kakashi who, as the translators reported to us at the end of chapter 17, has died. I think it’s a real shame to lose such a great artist – as you’ll see in the images below he had a talent for drawing hot girls and sexy scenes. But not just his artwork, the way he uses panels makes it a nice, flowing easy read – one of the mangas strengths!

Sadly, the gist of it is, the 17 currently translated chapters are probably all we’re gonna get :\

Let’s have a look at them..

One interesting thing about this as an ecchi manga is that the ecchi isn’t constant with tits and panties being crammed into every page, but rather it builds up to a climactic erotic scene every few chapters.

The first chapter doesn’t beat around the bush though, quickly introducing us to a topless school girl, the main girl of the story, Asagiri, presenting her superb breasts for fondling..

Things go south quickly when Doumeguri reaches into her panties..

Of course, it couldn’t be that easy as she turns out to be a virtual recreation of Asagiri.

From here, after a bunch of plot, his whole class gets caught up in a virtual world and the MC finds himself suddenly having to be the demon lord of an evil army, hiding his identity behind full body armour.

While walking his castle he bumps into a working slave, who turns out to be one of the girls pulled into the world, Aikawa, (she ended up in a much less desirable position!). It seems slaves aren’t granted panties as he gets a clear view at her lower area.

After they have a bit of a catch-up they are interrupted by one of his generals – the sexy but devious Fernious. She questions the way they are interacting, which quickly escalates into them having to roleplay a master/slave ecchi scenario to keep their identities a secret.

As you can see, things escalate quickly.

Forneous however is not entirely convinced and opts to join in herself to investigate first-hand.

Doumeguri manages to turn the tables and gives her a good lewding while Asagiri watches on, clearly a captive audience.

When walking through the castle, they have to play up the slave factor so he walks her around in chains so as not to rouse suspicion.

Back to Asagiri now, who gets some nice full-page art. Doumeguri goes undercover with the heroes side and winds up paired with Asagiri. After things go awry they end up together in a cabin clothed only in sheets.

Back to his demon lord role and he’s greeted with a harem of succubus, organised by his underlings.

The final climax of the manga comes now as Doumeguri has to curb the fighting spirit of one of his captured classmates.

For whatever reason. he decides public erotic humiliation is the way to go about it as she stripped to her underwear before a throng of enthralled goblins.

Stage 2.. remove bra

Stage 3… farewell to panties..

And this is where it gets interesting as he uses magic to overwhelm her with pleasure.

She succumbs to horniness and puts on a show to remember, masturbating all the way in front of a live audience.

And finally, a nice shot of Aikawa.

It’s a real shame the mangaka passed away. As you can see, the artwork was really great for this manga. Our only hope now to continue this story is for the light novel to get translated!
