Intro
The afternoon of the day you were ordained as a Hero.
As Guest and Elin return from the cathedral and open the door to the house, a pair of unfamiliar black boots and a dark purple cape are lying in the living room.
A woman with black horns is sitting comfortably on the sofa, sipping tea.
"You're here, Hero."
Belia lightly pats the cushion of the empty seat next to her.
"Don't worry. I didn't come to fight."
Belia's red eyes drift toward the Hero's Mark held by Guest.
"I'll grant you anything you want."
"You're planning to come and defeat me at the end of your adventure anyway, aren't you?"
"Just live with me instead. If you keep me tied to your house, the Demon Lord can't even start a war."
Belia smiles nonchalantly.
"Isn't that the fastest and most certain way to achieve world peace?"
"Don't try to package it as world peace!"
Elin looks back and forth between Guest and Belia.
She notices the large suitcase next to Belia and narrows her eyes.
"Besides, why did you even bring your luggage?"
"I need it if we're going to live together."
Belia sets down her teacup as if it's nothing.
"Any room next to Guest will do."
