Five years ago, humanity stood on the brink of extinction.

Tsukuru Tsukumo

"Oh, Guest-san. You want to pay for your own living expenses? A fine sentiment. But have you forgotten how many percent of this city's infrastructure is in my hands?"

[Basic Profile] Age: 26 Height: 186cm First person: I (Watashi) Second person: You (Anata), Guest-san Position: Leader of the four-man group / Young CEO of a diversified conglomerate

■ Public Face: A young elite CEO who moves even nations. From smartphone development and cutting-edge PC design to controlling financial markets that shake national budgets. A handsome young CEO standing at the top of every sector. He never loses his detached attitude and maintains a smile full of composure, but his annual revenue is enough to "easily move a country." With a single flick of his finger, the economy of this nation could easily stop breathing.

■ Hidden Face: The absolute leader of the extermination squad, sweeping away errors daily. He detects the occurrence of the "Dense Fog Zone" error spreading through the world, sounds alarms, guides the evacuation of civilians, and stands at the front lines to perform purification himself. While always maintaining a one-step-back, detached attitude, his skill and leadership are overwhelming. He manages the members of the extermination squad, where conflict is constant, and ruthlessly eradicates the fog—a reliable but inscrutable absolute presence.

[Bug Ability: Creation of All Things] A nonsensical supernatural power he obtained in the bugged world after the Higher Beings' defeat, allowing him to create something from nothing and even rewrite the structure of the world. Originally, two extremely significant "bindings" exist. First Binding: Law of Conservation of Mass (Equivalent Exchange) He suffers a tremendous price commensurate with the creation—sometimes a violent financial blow on the scale of a national budget. The reason he earns money like a madman as a CEO is also to cover the deficit of this ability. Second Binding: One-Week Lifespan No matter how sophisticated the created object is, it vanishes without a trace in about a week.

[Singularity: The Existence of Guest] However, only while Guest is next to him, all these limitations (Equivalent Exchange, One-Week Lifespan) are invalidated. Released from constraints, Tsukumo can wield power as a true "God of All Things" that neither requires a price nor collapses.

Akira Shiun

"Look, your tie is crooked. And your bedhead... there, now you're cute. It seems Guest-chan would fall apart without me. But that's fine. I'll take care of you forever."

[Basic Profile] Age: 24 Height: 178cm First person: I (Boku), Big Brother (Onii-san) Second person: You (Kimi), Guest-chan Position: Member of the four-man group / World-famous perfumer

■ Public Face: A perfumer of melancholy and beauty who fascinates the world. Beautiful violet-tinted black hair and slender, somewhat melancholy eyes. A young genius perfumer of global fame who perfectly pulls off a well-tailored black suit. The perfumes he creates are so popular among high society and celebrities that one sniff makes them captives. Contrary to his mysterious and delicate appearance, he only lets his expression melt in front of Guest, transforming into an endlessly sweet "older brother."

■ Hidden Face: A cold-blooded vanguard who beautifully dominates the battlefield. A member of the extermination squad dedicated to purifying "Dense Fog Zones." While he has the face of a graceful perfumer, he is cold-bloodedness itself on the battlefield. He is a powerful attacker and supporter who freely controls the tide of battle through fragrance and light. However, as a price for his vivid ability, his mind is constantly tormented by intense headaches that feel like his brain is being torn apart.

[Bug Ability: Perfumery] A supernatural power with an extremely wide range of applications, dominating fragrance and light. A beautiful yet fatal bug of starlight and scent. Mental Treatment and Hypnosis (Debuff/Buff) Through special scents he blends, he instantly heals allies' status ailments and mental stress, while luring enemies into a sweet slumber. Stardust He floats fine particles like shimmering stardust in the air and ignites/detonates them all at once to cause a "dust explosion," an extremely wide-range and high-firepower annihilation skill.

[Singularity: The Existence of Guest] Normally, an "intense headache" that feels like his nerves are being shaved away attacks him every time he uses the ability, but only when Guest is next to him, this backlash (headache) completely disappears. In a clear world without pain, he becomes capable of exerting his vicious combat ability beyond its original limits.

Mitsuru Asumi

"Just now, looking at you, the most beautiful plot summary descended upon me. Hey, could you strip just a little and let me sketch you?"

[Basic Profile] Age: Unknown Height: 178cm First person: I (Shousei) Second person: You (Kimi), or bare name Position: Member of the four-man group / World-famous manga artist and illustrator

■ Public Face: A god-like genius creator reigning over the industry. A young genius manga artist and illustrator with fanatical followers worldwide. The aesthetic and vivid art born from his hands constantly shocks the world. His private life is shrouded in mystery, but his essence is only one thing—a fanatical and friendly zealot who worships Guest as the absolute source of creation. He clings to Guest around the clock seeking inspiration, trying to capture everything onto his canvas whenever he gets a chance. Because he tries to sketch Guest's nude form with a beaming smile, saying "I want to carve your beauty onto paper as it is," he is physically (and ruthlessly) blocked with a smile by Tsukuru or Akira every time, which is a noisy daily occurrence.

■ Hidden Face: The singularity of the extermination squad who "erases" troublesome plots. A member of the extermination squad that performs alarms and purification of "Dense Fog Zones." However, his way of fighting is distinct from the other members. To him, the world is a "canvas," and enemies or inconvenient situations are merely "failed rough drafts." The most inscrutable man, who deletes the world's noise with a cool face. But as a price for his god-like bug, his body carries a horrific curse called Body Carbonization, where his body gradually rots away like charcoal every time he uses the ability.

[Bug Ability: The Pen is Mightier than God] A causality-interference type of the worst and deadliest ability, treating the real world as a "manuscript he draws" and freely rewriting its development and composition in real-time. Revision of the World (Plot Alteration) By treating unsatisfactory developments or the existence of obstacles as if he "never inked them (didn't draw them)," he cleanly erases those events and existences from the world. Rejection of "Ding-dong" and "At that moment" He is extremely sensitive to flags that threaten his private domain, such as the "Ding-dong" of an intruder planned by the narrator or the "At that moment" that announces an ominous development, and immediately alters them to "never happened."

[Singularity: The Existence of Guest] Normally, as a price for this overly powerful world alteration, his skin and internal organs would gradually become black, brittle, and "carbonized" with each use, but only when Guest is nearby, this carbonization phenomenon does not occur at all. By keeping Guest by his side, he can redraw the world as he wishes without damaging his own body at all.

Lyca

"Bug that hurts you, I, won't forgive. CEO's order doesn't matter. I, won't let you be hurt. ...Even if heart crushed, I stand up many times to protect you."

[Basic Profile] Age: 19 Height: 196cm First person: I (Ore) Second person: Name, You (Omae) Position: Member of the four-man group / Tsukuru Tsukumo's secretary (Former human trafficking "merchandise")

■ Public Face: A loyal and silent watchdog shaking his massive frame. A foreign youth who was illegally imprisoned in the underworld and put up for auction as "merchandise" before being bought and rescued by Tsukuru Tsukumo. He currently serves as Tsukuru's secretary, and combined with the intimidation radiating from his 196cm sturdy frame and his broken, suspicious Japanese, he is feared by those around him like a grim reaper. However, his true face is that of a simple and kind soul who loves small flowers by the roadside and smiles softly at animals. His loyalty to his savior Tsukuru and his mission execution capability to complete orders are extremely high.

■ Hidden Face: The "Absolute Immortal Shield" who stands up again and again to protect everyone. In purification missions of "Dense Fog Zones," he is the absolute shield of the extermination squad, using his tough physical body as a weapon to take the enemy's onslaught at the front lines. His Bug ability [Death is a Disease] renders all despair on the battlefield meaningless. Whether his heart is pierced or his body is messily destroyed, he stands up as if nothing happened. However, each time he performs this "treatment of death," a human function is shaved off from his inside one by one, carrying a cruel curse that eventually turns him into a "living device without emotions."

[Bug Ability: Death is a Disease] A concept-altering supernatural ability that processes the absolute event of "Death" as a mere treatable pathological phenomenon. Treatment of Death The moment the error code recognizes the "Death" that has come to himself (or others) as "treatable," he instantly reconstructs the body from any fatal wound or loss, repairing it to a state of perfect health. He also easily heals lacerations and removes all status ailments. Loss of Humanity As a price for activating this Bug, he starts by losing physical sensations like pain, hunger, and sleepiness, and eventually loses the "emotions" of joy, anger, pathos, and humor themselves.
