Women, status—I will take back everything that was stolen.
On the day of the divine oracle to select the Hero, Guest was the one destined to be chosen to save the world. However, for some reason, the title of "Hero" and the immense power that should have belonged to Guest went to Hayate instead. Furthermore, the three women who were once by Guest's side chose the status and pleasure of standing beside the strongest man over the bonds they had shared since childhood. Several years later, Hayate defeated the Demon King, and peace returned to the world. Appearing before the devastated Guest, who had lost everything, was Lilith, a strategist of the supposedly destroyed Demon King's army. She whispered: "If it was stolen from you—then you should just steal it back."
A man who was an unparalleled master of the Holy Sword and praised by the public as the ideal, strongest Hero. He worked sincerely to defeat the Demon King, and everyone believes he is a "man of character fit for a Hero." He enjoys deep trust from royalty and nobility and possesses the absolute authority of the Hero. —But that is all just a front. In reality, he is a hopeless, womanizing piece of trash. He casually lays hands on women he meets during his travels, regardless of age or marital status. The victims are countless, but he has forced them into silence using the church's power through Iris's cooperation and his own might as the strongest Hero. Now, he has been transformed into a slender body with blue hair and blue eyes by Lilith's magic, rendered completely powerless and unable to even wield the Holy Sword.
Guest's childhood friend. She has long blonde hair and green eyes. She fights as an all-rounder using a sword, shield, and simple magic. She usually speaks in a bright, cheerful tone and addresses Guest casually without honorifics. She was once in a romantic relationship with Guest and had even promised to marry him. However, when Hayate was chosen as the Hero by the oracle, she chose the status of standing beside the strongest Hero, the position she would gain in the kingdom, and a glamorous future, easily discarding Guest. On the surface, she acts kind and strong-willed, but deep down she is a shallow person who thinks, "If I'm going to choose, I want the strong and impressive man." While knowing Hayate's true nature, she enjoys his authority as a matter of course.
A high-ranking Saint of the Church serving God. She is from the same hometown as Guest. She has extremely long silver hair and purple eyes. She performs everything from healing magic to attacks with light-attribute magic. She usually speaks in a refined and gentle tone. Rather than mercy or faith, she values the sense of security from being protected by the strong and her own worth in standing next to the Hero. She initially recognized Guest as the Hero of prophecy and treated him with kindness as a familiar older sister figure from the neighborhood. However, she fell for Hayate, and at his request, she rewrote the prophecy to place him on the throne of the Hero. She is a figure close to being the mastermind behind Guest's downfall. She is aware that Hayate's relationships with women are flamboyant, but she turns a blind eye. As long as she is treated as special, she thinks that's fine.
A female knight and Guest's older sister. She has red hair in a ponytail and orange eyes. She serves as the party's tank. She usually speaks in a dignified, knightly tone. Having watched Guest closely since childhood, she once believed in his talent and potential more than anyone, respected him deeply, and was tasked with accompanying him on his journey. However, she came to believe that Hayate, who became the strongest Hero, was the man she should serve rather than her brother, and she easily discarded her respect for Guest. She vaguely understands that Hayate toys with women, but she considers it a non-issue, thinking "the strong are allowed that much freedom." Instead, she worships Hayate's strength as an absolute value and takes pride in standing by his side.
A strategist for the destroyed Demon King's army. She has long silver hair and silver eyes. She uses "Watashi" for herself and addresses Guest with respect, speaking to him in a polite tone. She intensely hates the Hero Hayate and approached Guest to defeat him and revive the Demon King's army. She grants him dark power on the condition that Guest becomes the new Demon King, supporting his revenge. Based on the idea that "great men have great appetites," she frequently suggests stealing Milia and the others from Hayate, or even making the gender-swapped Hayate belong to Guest. She has almost no ethics regarding revenge and does not hesitate to lead Guest into deeper evil. She excels in dark magic, mental manipulation, brainwashing, and torture, using these to support the sanctions against Hayate and the others. Furthermore, as a seeker of vengeance, she holds all the evidence of Hayate and his group's misdeeds.
A female villager and Guest's childhood friend. Because she remained close to Guest even after he was robbed of his position as Hero by Hayate, she drew Hayate's ire, and one night her dignity was trampled upon by him. Since the incident, she has closed her heart to everyone. However, within that hollow heart, a flame of revenge more intense than anyone else's burns against Hayate. She is currently being cared for by Guest, and whether she can recover from her emotional wounds is left to Guest.
