The battle against the forces of evil is nearing its end as the Undead King Leonis Death Magnus remains the sole survivor of the Dark Lords. Standing no chance alone against his enemies, Leonis seals himself deep underground with the goal of reincarnating a thousand years later and rebuilding his demonic army.

Within the span of a millennium, however, everything has changed. People no longer remember the great war that led to Leonis' defeat and instead face a new threat—the monstrous creatures known as Voids. Magical devices have replaced sorcery, and humans with special powers—manifested in the form of weapons called Holy Swords—train at the Excalibur Academy to fight the Voids.

Reborn as a 10-year-old human boy, Leonis meets Riselia Ray Crystalia, a dutiful girl who stumbles upon the ruins of his hibernation chamber. Believing that Leonis has amnesia, Riselia offers him guidance and enrolls him at the Excalibur Academy. Leonis still intends to take over the world, but he must first familiarize himself with a reality completely different from all he knows.

It's a reverse LOLI anime, With kid fatish women. Dang it's kind of fukin creepy and uncomfortable watching a 10y kid getting booty from 16 year old girls who call him lil brother.

But also there is no romance or harem. I don't think anyone have any romantic feeling over the mc.(jUst want to suck his blood) and nor he shows his powers and surprise everyone type of shit.and the side characters are just there to make our 10 year demon Lord getting chumi over their body

But a demon Lord who hate human is simping over a human's body is kinda idiotic writing(Anos voldigod ...

Mixed Feelings
A simple fantasy sci-fi anime with surprises in it, though with some nice and smooth animation.

This show revolves around a demon lord that is defeated and decides to hibernate for a thousand years. To then wake up in the future with a weaker form and where humans have forgotten how to use magic, and technology now mostly rules. You then follow how he becomes a part of a squad only made up of women, and has made strong relation to one of them.

The plot in itself is in no way mind baffling, and is honestly very predictable with little to any plot twists. The plot ...

The Demon Sword Master of Excalibur Academy — the definition of the LN BS trope done a thousand times and more, which sounds different, but honestly looks no different from many of its contemporaries.

For the record, novelist Yuu Shimizu is one of those authors that you don't know much about. That is unless, you've read or even seen Seireitsukai no Blade Dance a.k.a Blade Dance of the Elementalers, which got TNK's anime adaptation almost a decade ago in Summer 2014, which to me is one hell of a guilty pleasure of a source material when both the school and harem genres were a riot back ...
