AN OLD FRIEND RETURNS With a holiday called the Holy Light Festival fast approaching, the girls of the eighteenth platoon decide to host a haunted café in their dorm. The event is meant to celebrate the arrival of the Sixth Assault Garden, home to Elfiné’s older sister, Clauvia. The mischievous woman is part of a research team that recently made an incredible discovery in the northern tundra—a massive creature sealed in impervious ice. Much to his astonishment, Leonis recognizes the winged beast as an old rival he never managed to beat. When the monster is set loose to wreak havoc, will Leonis manage to take it down in time?

Battles for ancient kingdoms are nothing compared to the battles of a classroom! Awakening from magical stasis after a thousand years, the Dark Lord Leonis suddenly finds himself in the body of a ten-year-old boy! He quickly meets Riselia, a girl confronting the Voids, creatures that have nearly exterminated humanity. Determined to uncover the mysteries of this strange new era, Leonis enrolls in Excalibur Academy, a school that trains students to fight back against these enigmatic monsters. Could the Voids hold some connection to Leonis's past?

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 MYSTERIOUS HIJACK ON THE HIGH SEAS! When a princess visits the Seventh Assault Garden, Leonis believes it’s a chance to expand his influence as a Dark Lord. Unfortunately, the celebrations are cut short by a Void attack. Things get only more treacherous when a rebel group seizes control of the princess’s ship! Leonis and the rest of his squad plan to retake the vessel, but there appears to be more at work than a simple insurrection. And why does Regina seem to know so much about the princess?

THE GODDESS’S CALL ​A recent rash of incidents has seen Holy Swords spiraling out of control and becoming twisted weapons known as Demon Swords. No one is sure as to the cause, but every Holy Swordsman affected claims to have heard the voice of a goddess, a detail that catches Leonis’s attention. However, there’s no time to investigate, as he and the rest of the eighteenth platoon are sent on a mission with other students to eradicate a Void Hive that crops up in Necrozoa—the site where Riselia found Leonis. So many Voids appearing in such a conspicuous place…could this be connected to the Demon Swords and Leonis’s past?

THE PRICE OF VENGEANCE Nine years ago, Sakuya lost her home and sister to a powerful Void Lord. She’s dedicated her life to fighting the Voids ever since. However, when a group of the Sakura Orchid’s greatest fighters, the Kenki Gathering, contact her with a plan to use the Seventh Assault Garden as bait for the Void Lord, she’s left in a difficult position. While she wants revenge, it can’t come at the cost of her new home, but Sakuya can’t stop the Kenki Gathering by herself. Fortunately, she knows someone who might be able to help...a Dark Lord!
