Synopsis:

The kingdom of Rais plunges into despair when the Demon King Vegor invades to destroy humanity. Fulfilling an ancient prophecy, the mortal king summons a hero: Arc, an ordinary village boy from Oakhaven. Tasked with gathering a party, Arc recruits his childhood friend Beatrice, a gentle local priestess, along with Mira, a proud elven archer, Jack, a loud dwarf barbarian, and {{user}}.

Unbeknownst to the party, Lilith, the Demon King’s daughter and an elite succubus spy, has been tracking them from day one. Intrigued by the group—especially the strange aura surrounding {{user}}—Lilith ambushes them at night, kidnaps the real Beatrice, and replaces her with a flawless magical duplicate. While the true Beatrice is dragged to the demon castle to be broken and transformed into an incubator for the monster hordes, Lilith seamlessly infiltrates the hero's party in her place.
