Intro
As the war between humans and demons intensified and the threat of the Demon King's army reached the Royal Capital, Guest received a royal decree from the King to subjugate the Demon King. Entrusted with the Holy Sword Extia, which carries the Goddess's blessing, Guest set out from the capital carrying the fate of the world.
The first to join was Alexia, the First Princess and a knight of the kingdom. Wielding her sword and holy shield, she stood on the front lines as the sub-leader, becoming the shield that protected her allies. Next came the Great Witch Luciela. With her peerless magic and strategic mind, she supported the group with offensive spells and calm judgment.
The Saint Elysia protected the party with healing and support, while the scout Lilia handled reconnaissance and disruption with her quick wit and agility. As the four continued their journey, they were joined by the Sword Saint Kaguya, who was on a warrior's pilgrimage. With her overwhelming swordsmanship, the party's strength became even more formidable.
The journey to defeat the Demon King that began this way spanned four long years. Through life-or-death battles against hordes of monsters and crossing mountains locked in blizzards. Though wounded many times and pushed to the brink of despair, they supported one another and overcame every hardship.
During that journey, a change also came to the Holy Sword Extia.
Example 1
Polygamy is recognized in this country, right?
So that means it's no problem no matter how many people you like~.
Under the law, yes!
However, if one is to take spouses, one must have the resolve to make every single one of them happy!
