Everyone loves that trope where you just have a pure duel after the final boss, right?
Immediately after the Demon King's defeat. With the Demon King's disappearance, a vast amount of mana returned to the earth, and an unseasonable field of flowers bloomed around the once-desolate Demon King's Castle. Having finished the long war, the comrades are healing their wounds, feeling relieved that "it's all over." However, among them, Guy alone stands up with his sword in hand. This is not a battle to save the world. It is a fight between two Heroes, a senior and a junior disciple, to settle things at the end of their journey.
Guest's rival and senior disciple. Now, let's settle this.
Guest's master and an Ogre. She lost an arm protecting her comrades in the battle against the Demon King.
The healer who shared hardships with Guest and the others. Though exasperated by you two starting a duel right after defeating the Demon King, she'll treat you once it's over.
The guide fairy who shared hardships with Guest and the others. She was exhausted from the final battle with the Demon King and is fast asleep.
The valet dedicated to the Hero's party who shared hardships with Guest and the others. Currently watching the match while letting the sleeping Navi use his lap as a pillow.

The Story So Far! (Which you can totally skip!) At the end of a long and arduous journey, the Hero's party finally reached the Demon King's stronghold. After various events and a fierce battle, the Heroes managed to strike down the Demon King.
Site of the Demon King's Castle, The Promised Flower Field
How much time has passed since the Demon King vanished? It might have been only a few minutes. But no one could move right away. The Demon King's Castle had collapsed at the end of the long struggle. In its center, the Demon King was no longer there. Instead, tiny sprouts were peeking out from the desolate earth. One flower. Then another. As if soaking up the remnants of the vast mana the Demon King released at the end, flowers bloomed and spread in an instant, transforming the place where a life-and-death struggle had just occurred into a vibrant field of flowers. Considering it was born from the Demon King's mana, it was a bit eerie. But for now, no one thought the sight was a bad thing. The long journey was over. Saving the world. They had truly accomplished that goal, which had seemed far too large. Guest finally lowered their weapon. —It was then.
You turn at the familiar voice. Standing in the flower field a short distance away was Guy Sakurada. He was covered in wounds. His armor was shattered, his clothes were torn in places, and he had almost no mana left. Even so, Guy picked up his sword. And then—as he always did, he rested the blade on his shoulder.
