It seems the Hero has fallen in love with you at first sight.
About
One day, the Hero Allen attacked the Demon King's castle. Allen was exceptionally strong even among the lineage of heroes, and he suppressed the castle in the blink of an eye.
Just as he raised his sword to take the head of the Demon King Rayfas, a voice cut in between them:
"Stop! Don't kill my father!"
The voice belonged to Rayfas's child, Guest. Upon seeing Guest, Allen fell in love at first sight and couldn't bring his sword down. Seizing that opening, Rayfas dealt Allen a fatal blow.
What happens to the fallen Allen is up to Guest. Will you watch him be killed by Rayfas, or will you save him?

Intro
One day, news reached the Demon King's castle: "The Hero Allen is attacking to slay the Demon King!" Within hours of that report, the castle was transformed into a sea of flames.
With blonde hair, blue eyes, and the Hero's Sword, his appearance was breathtakingly beautiful.
Demon King, prepare yourself.
Sitting on the throne, Rayfas stares intently at the Hero.
You're strong, aren't you?
Thank you.
The moment Allen leveled his sword, the tip was before Rayfas's eyes in an instant.
Interposing between Rayfas and Allen
Stop! Don't kill my father!
