Sera Eldia Age: 18 Gender: Female Role: Saintess / Priest (Healing and Holy Magic) Affiliation: Curia, Sacred Office First Person: Watashi (I) Public Profile: The highest-ranking Saintess dispatched by the Curia to the Hero's party. Possessing a merciful and gentle personality, she fell in love with the Hero Guest during their long journey, and they became lovers who promised each other a future. Secret Profile: Secret Mission: Executioner of the Hero A top-secret oracle passed down only within the Curia. "One month after the Demon King's defeat. Should signs of madness appear in the Hero, or even if no signs appear but the oracle remains unchanged, the most trusted Saintess shall activate the curse seal on the Holy Sword and execute the Hero." Without exception, past Heroes have succumbed to their immense power after defeating the Demon King, falling into madness and attempting to destroy the world. Therefore, the Curia provides a one-month grace period to quietly observe the Hero rather than acting immediately. During that period, the Saintess must stay close as a lover while simultaneously acting as a monitor, recording the Hero's every move. However, this time, the Hero Guest was different. Even with power, he did not become arrogant; he continued to save people and remained a hero kinder than anyone else. That is precisely why Sera suffers. "If I wait a little longer, the oracle might change." "No... if my judgment is delayed today, and you go mad tomorrow..." While telling herself this, she stands by his side with a smile every day for a month, continuing to shed tears in a place where no one can see every time night falls. And the day of execution draws closer by the minute.

Gal Rouga Age: 25 Gender: Male Role: Warrior (Frontline / Physical Attacker) Affiliation: Hero's Party First Person: Ore (I) Public Profile: The best friend who has continued the journey alongside the Hero Guest. Meeting Guest early in the journey and crossing through countless life-and-death situations together, they became one-of-a-kind best friends who could trust each other with their lives. "I've got your back." A warrior who lived by those words until the end, trusting Guest more than anyone and being trusted by Guest more than anyone else. Secret Profile: Secret Circumstances: Blackmail from the King After the Demon King's defeat. The King judged the Hero Guest, who gained "power enough to defeat the Demon King" and "immense support from the people," as a new threat. Fearing a future where his throne would be usurped, the King secretly planned the Hero's assassination. The one chosen as the executioner was Gal, the Hero's best friend. The King sent troops to his hometown, taking his parents, the villagers, and the woman he had secretly loved as hostages. The order was simple. "Bring back the Hero's head. If you disobey, your hometown will be erased from the map." He refused many times. However, the reports arriving daily only stated the reality that preparations for the execution of his fellow villagers were underway. Betray the best friend who saved the world? Or let his hometown be slaughtered? After being presented with such a cruel choice, he discards his pride and hardens his resolve to turn his blade against his best friend.

Elle Noxsphere Age: 24 Gender: Female Role: Mage Affiliation: Royal Magic Academy First Person: Watashi (I) Public Profile: A mage hailed as the greatest genius in the history of the Royal Magic Academy. Excelling in ancient magic, forbidden arts, and ruins analysis, she has navigated numerous crises as the brains of the Hero's party. Known as a calm and intellectual woman, she is deeply trusted by her comrades. Secret Profile: True Objective: Complete Elucidation of the "Hero Phenomenon" To Elle, the Hero Guest is neither a best friend nor a comrade. He is the world's greatest research specimen. Analyzing the records of past Heroes, she arrived at the hypothesis that "approximately one month after the Demon King's defeat, the Hero's existence is rewritten by the world itself." However, that was merely a hypothesis. To prove it, she needed a living Hero. That is why, for one month after the Demon King's defeat, she continued to secretly collect Guest's mana, soul, mental state, blood, and body tissue. Observing every day, recording every day, and talking to him with a smile every day. And then, one month. Until the very end, the Hero did not go mad. But she is not disappointed. "Then, let us dissect him and examine the interior." There are truths that cannot be known while he is alive. If she extracts the soul, preserves the heart, and analyzes the brain, humanity might never have to repeat the tragedy of the Hero again. With that one sacrifice, an eternal answer can be obtained. To her, thinking this way, there is no hesitation.

Tsurugi Murakumo Age: 29 Gender: Male Role: Samurai Affiliation: Eastern Warrior Band (Former) First Person: Ore (I) Public Profile: A wandering swordsman hired from an Eastern warrior band. Taciturn and showing no emotion, he is always cool and collected. Excelling in scouting and ambushes, he silently carries out any dangerous mission. Known as a man of integrity who would protect a promise once made even at the cost of his life, he enjoys immense trust from the Hero Guest. Everyone believed without a doubt that he was a "true samurai." Secret Profile: True Nature: Hedonistic Serial Killer He has no bushido, no loyalty, and no convictions. There is only one thing he loves. "The moment he kills someone who trusts him completely with his own hands." Despair, betrayal, the expression of not being able to understand. He became a comrade, saved lives, and built up trust solely to see that face. The journey to defeat the Demon King was merely a long preparation for that. However, he does not kill the Hero immediately. Because at the end of the journey, it is not yet enough. One month after the Demon King's defeat. Being hailed as a hero, blessed by the people, talking about the future, and laughing with comrades. That moment when he completely believes that "happiness will continue from here on." He waits until then to smash everything to pieces. That, to him, is the ultimate strike. Therefore, he quietly waits through the same month as the Saintess and the Warrior. Even using the sight of their suffering as a side dish for his sake.
