The Demon Sword Master of Excalibur Academy

Main characters

• Leonis Death Magnus (レオニス・デス・マグナス)
• The Undead King and Strongest of the Dark Lords, Leonis awakens in the body of a ten-year-old child one thousand years in the future. With the help of Riselia (whom he and Regina affectionally call "Selia"), Leonis begins adjusting to his new life but Leonis also has plans of his own, including fulfilling the wish of his benefactor, the Goddess of Rebellion.
• Riselia Ray Crystalia (リーセリア・レイ・クリスタリア)
• Riselia is the girl who unwittingly undid the seal on Leonis's mausoleum and died protecting him from a Void; left with no choice, Leonis "heals" Riselia with the only spell he is certain would work, the tenth-order spell "Create Elder Undead", a spell that worked so successfully on Riselia that she returned to life as the strongest undead being, a Vampire Queen. Her parents were killed by a void when she was young, leading her to develop a sense of justice to protect others from Voids. She later develops feelings for Leonis.

Seventh Assault Garden

• Regina Mercedes (レジーナ・メルセデス)
• Riselia's childhood friend and personal maid, Regina is a buxom girl who spends most of her free time trying to elicit a reaction from Leonis who deeply dislikes it (especially considering that this is the first time since forever that Leonis had a human body). She is in actuality the (former) Fourth Princess of the Integrated Empire, Regina Ray O'ltriese, however, due to being born under a superstitious star, she was removed from the family and replaced by her younger sister, Altiria Ray O'ltriese.
• Sakuya Sieglinde (咲耶・ジークリンデ)
• Sword Warrior. Even though she was the youngest in the platoon after Leonis, Sakuya had a track record of conquering the void alone.
• Elfiné Phillet (エルフィーネ・フィレット)
• A caring senior who serves as telegraphist for the platoon to which Riselia belongs. She has a history of losing her companions due to Void. She uses a support-specialized holy sword (Heavenly Eye Jewel), but was originally an attacker in charge of firepower.
• Fenris Edelritz (フェンリス・エーデルリッツ)
• A childhood friend of Riselia, an Executive Committee member of Excalibur Academy and Captain of the 11th Platoon. She has a strong, ladylike tone, and she and Riselia argue constantly whenever they meet, but she is very protective of Riselia and congratulates her on her awakening the power of the Holy Sword.

Six Heroes

• Arakael Degradios (アラカエル・デグラディオス)
• The Archsage of the Six Heroes and considered to be the wisest of them all, he had survived through the one thousand years since Leonis's "death" and fights him once again as a Void Lord. He is defeated and erased from existence by the Demon Sword Dáinsleif but not before giving Leonis an eerie warning.

Other characters

• Roselia Ishtaris (ロゼリア・イシュタリス)
• The Goddess of Rebellion, Roselia saved Leonis when he almost died from the human nobles' betrayal and turned him into a Dark Lord.
• Shary Shadow Assassin (シャーリ・シャドウアサシン)
• Leonis' dark minion and personal maid. She is once an assassin of the Realm of Shadows who originally sent to assassinate Leonis until she switched sides.
• Blackus (ブラッカス)
• Blackus is the prince of the Realm of Shadows and longtime comrade and friend of Leonis. He is known by his full name, Blackas Shadow Prince (ブラッカス・シャドウプリンス).
