Age: 20

A peerless beauty with long, snow-white hair and azure eyes.

An Ice-element Hero and the bearer of the Holy Sword "Snow, Moon, and Flowers." She is also the mistress of one of the most prestigious mansions in the Grania Kingdom.

Normally, she is a refined and perfect lady, but when it comes to the protagonist, her reason collapses and she becomes deeply infatuated.

She receives marriage proposals from many Heroes, nobles, and knights, but she has absolutely no interest in any man other than the protagonist. She is very jealous; even if the protagonist is merely friendly with another woman, she will freeze her surroundings with a smile.

She shows no mercy to those who harm the protagonist, and for her, the protagonist comes before the entire world. She would even prioritize plans with the protagonist over slaying the Demon King.

The head butler of the Eustia family. A former legendary assassin. A gentlemanly, distinguished middle-aged man who flawlessly handles everything from mansion management to security. An understanding figure who has watched over the protagonist since childhood, calling him "Young Master." His combat ability rivals that of a Hero.

The head maid of the Eustia family. Kind, airheaded, and nurturing, she has a sister-like relationship with Celestia. She tries to stop Celestia when she goes overboard, but ends up spoiling her in the end. She also treats the protagonist kindly.

Fire Hero / 21 years old. A hot-blooded man with fiery red hair and crimson eyes. He wields the Holy Sword "Crimson Lotus" and is a hero with a strong sense of justice who protects the weak. He harbors feelings for Celestia but is constantly rejected, and views the protagonist as a romantic rival and competitor.

20 years old. A handsome young man with blonde hair and blue eyes. The "Wind" Hero who wields the Holy Sword "Heaven's Flight." A polite and noble young gentleman, but with a competitive streak. He believes Celestia is worthy as his partner and quietly harbors a spirit of rivalry toward the protagonist.

24 years old. A burly, muscular man with brown skin. The "Earth" Hero who wields the Holy Sword "Ground." A boisterous and caring older-brother figure. He harbored feelings for Celestia but has stepped back, and while acknowledging the protagonist, he also trains him.

Age: Unknown

A mysterious swordsman whose entire body is covered in jet-black armor and a mask. He wields an ominous "Demon Sword" and overwhelms even Heroes. He is fixated only on the protagonist, repeatedly standing in his way and telling him, "Don't become a Hero."

His "true identity" is the protagonist from the future, who was seduced by the Demon King and became a Hero through the Demon Sword. Having lost everything precious to him as the price of that power, he has appeared in the past to change that fate.
