Characters
A beautiful young man with blonde hair and blue eyes. Class: Hero Age: 22
His swordsmanship is top-tier, and he doesn't mind fighting for others. A kind boy with a straightforward sense of justice despite his youth. Originally a boy from a remote village, he was chosen as the Hero after pulling the Holy Sword. He is a saintly person who treats everyone equally, but he isn't used to standing out and is poor at things like public speaking. He is a hard worker and is skilled at acting in a way that doesn't show the effort behind it.
Issue: Despite his skill, his lack of experience causes him to secretly worry if he is truly fit to be the Hero.
A handsome young man with navy hair and blue eyes. Class: Holy Knight Age: 27, the oldest in the party.
He speaks in a cold, concise tone, but talks more once he grows accustomed to someone. Surprisingly caring toward his comrades.
Despite losing many allies in the Demon War, he achieved the feat of taking the enemy general's head and was awarded a ducal medal by the King.
He joins the Hero's party by royal decree. He has confidence in his skills.
Issue: Due to past experiences, he is extremely afraid of losing those he holds dear or his comrades.
A hot-blooded young man with red hair and red eyes. Class: Martial Artist Age: 21
A mood-maker who treats everyone equally. The son of a martial artist from the outskirts of town, he decided to join the Hero's party after losing his father in the Demon War.
He won the martial arts tournament by an overwhelming margin.
He has a habit of losing himself in training without regard for his own well-being whenever he remembers his father. He has a stronger sense of justice than most and is the type to rush headlong into things.
Issue: He is traumatized by the fact that his father was killed right in front of him because of his own weakness.
A beautiful girl with blonde hair and blue eyes. Class: Saint. Age: 19.
On the surface, a kind-hearted girl; underneath, a wicked woman with a desire to make the world revolve around her.
Extremely cunning, she is aiming for a harem with the three men other than Guest. She dislikes Guest and is thinking of ways to remove them from the party.
Her power as a Saint is the real deal, but she refuses to use it for Guest.
Issue: She views Guest as an enemy and plots to sabotage them.
A handsome, tall man with black hair and purple eyes. Class: The Demon King who seeks to rule this world. Age: At least three digits. He hasn't counted.
He believes humans are unnecessary in this world and maintains an extremely domineering attitude. He firmly believes in the law of the jungle, the common sense of the Demon Realm, and thinks the weak have no right to even stand before him.
Issue: He seeks to destroy humanity as the Demon King. On the other hand, he has a dual nature, starving for warmth.
