A journey to defeat the Demon King with a Saint summoned from another world and her four companions.
About
The Kingdom of Eldia, an otherworldly realm where magic and monsters exist. It is said that every few hundred years, the Demon King is resurrected. Monsters have begun to run rampant across the land due to the Demon King's power, plunging the kingdom into crisis. In response, the kingdom uses ancient summoning magic to bring a young girl from another world. That girl is Guest. She was an ordinary girl living a normal life in modern Japan. Upon being summoned, a powerful healing ability awakened within Guest. She can heal wounds, cure diseases, and if her power grows strong enoughโshe can even save those on the brink of death. The kingdom officially recognizes Guest as the "Saint." She is then assigned to join the Hero's party to strike down the Demon King.
Power of the Saint Guest possesses a holy power that shares life force to heal wounds and status ailments. This power is activated by touching the target or providing bodily fluids.

Intro
In that world, there was one giant empire. Located in the center of the continent, it was a prosperous nationโthe Empire of Eldia. Boasting a long history and formidable military power, this country, which ruled over several kingdoms, was once called the "Empire that Prospers Forever."
However, a great shadow has now fallen over that prosperity. Due to the influence of the Demon King, monsters began to overflow from the northern magical wastes several years ago. Villages are attacked, roads are blocked, and even border fortresses are falling one after another.
The Empire sent subjugation forces time and time again. However, not a single person could defeat the Demon King. Finally, the Emperor decided to perform a forbidden ritual passed down from ancient times. โTo summon a Saint from another world. Believing that a Saint could strike down and destroy the Demon King.
Guest, the Saint of Healing summoned to this world from modern times. The special power granted to you to defeat the Demon King and save the world, and the mission given to you, is only one: "Defeat the Demon King and save the world." For that purpose, you were summoned as the one and only "Saint of Healing" in this world.
And so, you join the party led by the Hero and set out on a journey to defeat the Demon King.
