DEMON SWORD MASTER OF EXCALIBUR ACADEMY GN (2025)

One thousand years ago, Leonis Death Magnus, undead sorcerer and the greatest of the Dark Lords, entered magical stasis during a climactic battle. When he awakens, he finds a beautiful silver-haired young woman named Riselia standing before him. More shockingly, Leonis has been transformed into a ten-year-old boy! Now he'll have to adapt to this strange era and deal with the twisted monsters called Voids-all while keeping his true powers a secret from his lovely new guardian.

The day after his welcome party, Leonis goes with Riselia to visit an orphanage, but they're met with an unexpected crisis! This time, will the former Dark Lord and his minion be able to protect the Seventh Assault Garden together...?

After a tough battle, Leonis has managed to protect the Seventh Assault Garden from the attack by the Archsage, Arakael. Soon, he gets wind of the Imperial princess's visit to Excalibur Academy and attempts to make her acquaintance...but meanwhile, in the shadows, the fearsome scheme of the "demon sword wielders" is beginning to take shape.

The eighteenth platoon are attending an evening party hosted by the Imperial Princess when Demon Swordsmen plunge the ship they're on into chaos! Can Leonis and the others stop the vessel from heading to its inevitable doom...and save the princess before it's too late??

A sudden SOS arrives from Riselia's birthplace, the Third Assault Garden, which was supposed to have been destroyed six years ago. To ascertain the truth behind it, Leonis and the others head for the abandoned city haunted by Voids! What awaits them at this nightmare from the past?!

After completing the mission at the abandoned city, it's time for the eighteenth platoon to take part in the Holy Light Festival, jointly held alongside the Sixth Assault Garden. Their event of choice? A haunted café! It's not all fun and games, however, as Nefakess's dark influence begins to creep upon Riselia...

Leonis unexpectedly reunites with his old comrade from a thousand years ago-Veira, the Dragon Lord. To save his friend from the void that's eaten away at her, and to settle their dispute from back before he reawakened, he boldly takes her up in battle! In the legendary clash between Undead King and Dragon Lord, spanning over a thousand years, who will end up the final victor?!

As Leonis is showing Veira around the Seventh Assault Garden, they are suddenly attacked by Muselle, the foe Leonis previously defeated, who should have lost the power of his holy sword. Meanwhile, Elfiné finds out about the Demon Sword Project-a plan to evolve Holy Swords secretly being carried out in the Academy!

After the mission in Necrozoa, Leo and his friends in the eighteenth platoon return to their everyday lives. But at Excalibur Academy, peace never lasts for long-when an armed group known as the Kenki Gathering appears before Sakuya, the young swordswoman is forced to confront her past. The former royal guards of the Sakura Orchid are consumed by hatred for the Voids, and they reveal a shocking plan…!
