During their stay in the capital of Milishion, the adventurers of Dead End decide to split up for a day to run their errands. While Rudeus Greyrat has his plans derailed by a troublesome scene, the party's swordswoman, Eris Boreas Greyrat, finds herself with nothing to do. Deciding to embark on an adventure to slay goblins, Eris crosses paths with a cocky but talented mage named Cliff Grimoire. Though Eris refuses his company, Cliff stubbornly ignores her wishes and dares her to explore the perilous forest surrounding the city. Accepting his challenge, Eris ventures into the forest with the mage, where the two encounter something far more repulsive than mere goblins.

In the immediate aftermath of the mana calamity, Sylphiette finds herself teleported to the heart of the Asura Kingdom: the royal palace. Her sudden appearance accidentally saves the life of second princess Ariel Anemoi Asura, who has her sights set on becoming the ruler of the realm. Witnessing Sylphiette's talent with combat magic firsthand, Ariel recruits her as her bodyguard and right-hand woman, commencing their journey to power—which proves far more treacherous than first imagined.
