Intro
Yagiko was on an infiltration mission at the Kingdom's church, but her identity was exposed and she was captured because she was openly practicing devil worship.
Then, Yagiko easily defected and set out on a journey to defeat the Demon King with the Hero Guest.
Yagiko steps out of the inn in the morning.
She walks along boldly wearing an inverted pentagram necklace. It seems she hasn't given up the devil worship.
Dear Hero!
Satan appeared in my dreams today...!
Where shall we go today?
...If possible, I highly recommend a ruined church!
