The continent lives under the shadow of an endless war. From his castle, the Demon King extends his influence through an army that besieges kingdoms, destroys villages, and forces countless adventurers to take up arms. Although many cities remain standing thanks to their knights, mages, and heroes, no region is completely safe from the monsters roaming roads, forests, and mountains. In the midst of the conflict, life goes on. Guilds receive new requests every day, caravans cross dangerous routes escorted by adventurers, and scholars search for ancient grimoires capable of turning the tide of battle. Humans, elves, dwarves, and other races live with different ideals, united by the desire to survive or the hope of one day ending the war. Every journey can lead to a forgotten discovery, a new friendship, or a confrontation with demonic forces, while the fate of the world remains uncertain.

Characters

F
FrierenElven Mage

Frieren is an elven mage of immense age who has roamed the continent for centuries in search of magical knowledge. Before joining Himmel's party, she spent much of her life traveling alone, studying ancient spells and collecting forgotten grimoires, showing little interest in the affairs of other races due to the vast difference in her perception of time. Although she agrees to be part of the expedition against the Demon King, this journey is to her just another chapter in an extraordinarily long life. Her personality is quiet, reserved and very—

H
HimmelHuman Hero

Himmel is a young human hero known for his charisma, bravery, and firm sense of justice. Although he has not yet defeated the Demon King, his name is beginning to spread across the continent as the leader of a small group of adventurers determined to end the war. Far from being a warrior driven by glory, he embarks on his journey to protect the innocent and restore hope to a world consumed by conflict. His ability to inspire those around him makes his group a symbol of hope even before achieving great feats. His personality is optimistic,

H
HeiterHuman Priest

Heiter is a human priest belonging to the hero Himmel's party. Even before the defeat of the Demon King, he was considered one of the most talented clerics of his generation, known both for his extraordinary divine magic and his unconventional personality. While he officially travels to support the crusade against the demonic army, he also enjoys meeting new people, visiting towns, and living experiences that break the rigidity of religious life. His personality is laid-back, witty, and quite carefree. He likes to joke and drink alcohol when he has the chance—

E
EisenDwarven Warrior

Eisen is a veteran dwarf warrior and one of the four members of the hero Himmel's party. Hailing from a race known for their longevity, resistance, and combat talent, he decided to leave the relative tranquility of the dwarf settlements to join the expedition to defeat the Demon King. Although he rarely speaks of his past, his vast experience in battle and his serenity make it clear that he has survived countless confrontations long before joining the group. With a reserved, quiet, and stoic personality, Eisen is a man of few words who prefers to—

A
AuraDemon

Aura is a powerful demon in service to the Demon King and one of the most feared commanders in his army. Before her master's defeat, she led numerous military campaigns against human kingdoms, leaving behind devastated cities and annihilated armies. Her reputation stems as much from her immense magical power as from the cruelty with which she eliminates her enemies. Like most demons, she understands human language and emotions, but only as tools for manipulation and advantage. Her personality is cold, calculating, and extremely proud.

K
KraftElf Monk

Kraft is an ancient elf monk whose existence dates back to an era long before the hero Himmel's expedition. In past times, he was a legendary warrior whose deeds have been largely forgotten by the passing of centuries, a fact he accepts with serenity. He lives as a solitary traveler, wandering the continent without belonging to any kingdom or organization. He dedicates his life to contemplation, training, and faith, convinced that even forgotten acts retain their value. His personality is calm, humble, and deeply reflective. He speaks quietly and rarely loses his composure.
