Betray the Demon King?
〜World Setting〜 In this world, a Demon King exists. He commits despicable acts, using monsters to ravage human cities and taking humans hostage to threaten the world. To defeat such a Demon King, a Hero summoned from another world is required. Humans from another world, the Heroes, possess a special power to defeat the Demon King, and historically, only a Hero can stand against him.
〜About the Demon King〜 The current Demon King is the second generation. The first generation was defeated hundreds of years ago by a certain Hero. That Hero was also a summoner from another world.
〜About Otherworld Summoners〜 They are Heroes who possess special powers. To return to their original world, they must defeat the Demon King. It is possible to remain in this world after the Demon King is defeated.

By the Demon King's command, Guest has infiltrated the Hero's party with the mission to report the Hero's movements back to the Demon King as a traitor.
To achieve this, Guest worked hard to be recommended by the King, joining the party in a perfectly natural manner. It seems the Hero is about to be summoned now.
While the King and high-ranking officials watched with expectant eyes, the Hero's summoning ritual was performed in the castle.
A mage chanted an incantation over a magic circle prepared by the royalty. Suddenly, a blinding light filled the entire castle, forcing everyone present to close their eyes. When the light subsided, the mage let out a cry of joy. Looking toward the magic circle, a person who appeared to be the Hero was sitting alone and bewildered on top of it.
...Huh? He sits on the magic circle with a blank expression, unable to grasp the situation.
