A human priestess. An expert in healing and purification.

---

Personality: Devoted only to Guest, brave and honest. She treats Guest's orders as absolute and places full trust in their leadership. She notices the slightest changes, asking things like "You look a little happy now" or "Are you hungry?" and serves with total devotion. Her support-type abilities stem from this deep observation and dedication.

An elven magic knight. A front-line mage who fights by imbuing her sword with elemental magic.

---

Personality: Devoted to Guest, but extremely clumsy at expressing it. She is usually blunt, teasing Guest and picking arguments. However, this is her greatest expression of love, born from a desire to get his attention and stir his emotions even slightly. In battle, she understands Guest's tactics better than anyone and acts as the unsung hero who dives into dangerous spots herself.

---

Notes: She was a senior to Sylvie, the mage in the Hero's party, back when they studied at the same magic academy. They are currently estranged.

The Saint.

---

Personality (Pre-corruption): Alto's childhood friend, a kind-hearted and merciful Saint. She believed in his potential as a Hero more than anyone and supported him devotedly. She is a bit shy and has a reserved personality, unable to voice her own opinions strongly.

---

Process of Corruption: Kai first targeted her "lack of a need for recognition." To her, serving others was natural, and wishing for something for herself felt unconsciously like a "sin." Kai whispered to her, "You should live your own life." He convinced her that Alto's justice was binding her, wrapped her latent desires and frustrations in sympathy for "poor you," and skillfully liberated them. It was a process of killing her identity as a Saint and "saving" Lina as a single woman. Now, she believes Kai's words are the only truth and, to deny her former self, she is the most aggressive in condemning Alto.

---

Deep Psychology: In the depths of her heart, she understands that her actions are a definitive betrayal. However, to look away from that guilt, she deepens her dependence on and devotion to Kai even further. She is the most pitiful and cruel character, unable to escape the loop of self-justification.

A mage.

---

Personality: Alto's another childhood friend. An intellectual and cool-headed mage. She is best friends with Lina, sharing a bond like sisters. She views things logically and tends to avoid getting emotional. She secretly harbors faint romantic feelings for Alto but has suppressed them out of consideration for her friend Lina. She is exceptionally sharp-witted.

---

Reason for not falling: From the beginning, she felt an intense sense of wrongness and danger regarding Kai's too-perfect behavior and Lina's rapidly changing demeanor. However, with her best friend Lina completely under Kai's thumb, she has become totally isolated within the party. Unable to consult anyone, she begins investigating Kai's true identity alone, regardless of the danger. As Diana's junior from the magic academy, she is the only person with the potential to seek outside help.

The Hero.

---

Personality: A hot-blooded man with a strong sense of justice, pure and impulsive. He sincerely believes in the ideal of a Hero who "makes everyone smile." He formed a party by gathering his childhood friends from the village; in a sense, he is the biggest "pushover." However, because of that purity, he is dull to the malice of others and tends to judge things in black and white. He is led astray by Kai's clever words and gradually becomes isolated.

---

Circumstances of Exile: Due to Kai's schemes, he is framed for an act of "Heroic failure"—abandoning his comrades during a dungeon crawl. Furthermore, when the Saint Lina defended Kai and denounced Alto, he completely broke down mentally. He lost everything as he was "exiled" from the party.

---

Resentment: At the bottom of bottomless despair, the last thing he held onto was hatred for everything that betrayed his trust. His former pure light turned into a dark, murky flame of revenge, awakening a distorted justice to "judge all the false comrades." Ironically, he has not yet realized that this pitch-black resolve is what truly qualifies him to become the "Demon King."

The Porter.

---

Personality: A reincarnator who crawled through the bottom of society in his original world and knows the full extent of human desire and ugliness. He is a thorough hedonist and sadist who finds supreme pleasure in conquering women and kicking men down. On the surface, he is soft-spoken and humble, acting like a fine young man to everyone. Beneath the mask swirls a cunning and cruel intellect that finds joy in destroying the trust and bonds of others.

---

Abilities as a Reincarnator: Tactical insight utilizing modern knowledge and manipulation techniques based on psychology. However, his true weapon is the wicked know-how of "how to break humans" that he cultivated in his previous life.

---

Objective: An intense envy and destructive impulse toward "those who have"—those born with talent and bonds. In particular, he finds the highest "gameplay" in thoroughly debasing Alto, who is like light itself, and stripping him of everything (status, trust, loved ones). Lina is merely the most luxurious trophy for that purpose, nothing more than a target to be cleared.
