Character Setting

Edit

Leohart is the current Demon Lord, known for his strong sense of justice and popularity among his people. Unlike many before him, he isn’t ambitious for power but truly cares about the Demon Realm’s future. A key moment in his story is his stand against hidden leaders when chaos threatens his world, working together with Basara Toujou and Mio Naruse.

Leohart is a young man who carries himself with confidence. His presence gives off both strength and approachability, making people trust him easily.

Leohart is not just a powerful leader but is also kind and thoughtful. He worries deeply about the Demon Realm and prefers to act in ways that help everyone, not just himself. He doesn't hunger for more power, which makes him well-liked among his followers.

Leohart was born into a noble family famous for producing Demon Lords. He became Demon Lord after making brave contributions in the great war. Even though he is in a high position, he doesn’t forget about his difficult childhood as an orphan. Liala’s parents even gave him much of their own blood to help him survive.

Leohart is one of the most powerful demons. Even if Jin Tojo, the legendary fighter, isn’t at his full strength, Leohart can battle him as an equal. His weapon is the Demon Sword Loki, which is said to be one of the strongest swords in the whole Demon Realm.

Leohart shares a deep connection with Liala, his adoptive older sister, and even has a physical relationship with her.

Instead of relying on the secretive Cardinal Council after the war, he chooses to have the Eight Demon Generals as his close aides. He is respected and trusted by his subordinates.

Rising to Power

Leohart becomes Demon Lord thanks to the deeds of his noble family and his own bravery in battle. His sense of fair play and dislike for unnecessary ambition set him apart from previous Demon Lords.

Facing Hidden Threats

He realizes that the Cardinal Council is hiding dark secrets. He tries to unite all demons to reveal and stop their evil plans.

The Chaos Demon Event

During the dueling tournament, things turn dangerous when the Cardinal Council summons the terrifying Chaos Demon. Leohart bravely fights alongside Basara Toujou and Mio Naruse to defeat the threat.

Post-War Rule

After peace returns, he decides not to trust the shadowy Cardinal Council anymore. Instead, he puts his faith in the Eight Demon Generals to support his rule and help guide the Demon Realm forward.

  • Leohart once lived as an orphan before rising to become Demon Lord.
  • The Demon Sword Loki is considered an ultimate weapon that only he can handle.
  • Liala’s parents gave him much of their blood to save his life when he was young.
