7 Unbelievable Facts About All Fiction: The Reality-Erasing Power That Broke Medaka Box

Contents
As of December 21, 2025, the debate over the most overpowered abilities in manga and anime continues, and one name consistently dominates the conversation: All Fiction. This god-tier ability, wielded by the perpetual "loser" Misogi Kumagawa in the *Medaka Box* series, is not just about power; it’s about the fundamental denial of reality itself. It stands as a conceptual paradox, an ability so broken it forces us to question the very nature of what is "real" within the narrative. This deep dive will explore the latest and most comprehensive information on All Fiction, breaking down its terrifying scope, its strange limitations, and how it cemented Misogi Kumagawa's legacy as one of the most uniquely powerful characters in all of fiction. Prepare to have your understanding of what constitutes a "skill" completely rewritten by the ultimate Minus.

The Ultimate Loser: Misogi Kumagawa's Essential Biography

Misogi Kumagawa is the primary antagonist of the *Medaka Box* series, later becoming a complex anti-hero. He is the leader of the Minus student faction and is often referred to as the "Worst" due to his perpetual state of loss and his destructive mindset. Here is a quick look at the key facts about the wielder of All Fiction:
  • Full Name: Misogi Kumagawa (球磨川 禊)
  • Designation: Minus (A student with overwhelming, but fundamentally negative, capabilities).
  • Primary Ability (Minus): All Fiction (大嘘憑き, Ōru Fikushon), his second Minus.
  • Secondary Ability: Book Maker, which reduces the target to Kumagawa's level, making them a "Minus".
  • Notable Feat: He is credited with reforming Medaka Kurokami into her current personality.
  • Meta-Fictional Status: Kumagawa is aware that he exists within a work of fiction (a manga), often breaking the fourth wall.
  • Weapon of Choice: Giant screws, which he can summon and use to attack, though this is not part of All Fiction.
Kumagawa's entire character is built around the concept of loss, which ironically makes him the perfect vessel for a power that removes things from existence entirely.

What is All Fiction? The Power to Deny Reality

All Fiction is one of the most conceptually terrifying abilities in anime and manga because its function is not to destroy, but to *deny*. It is the ultimate form of a "Minus," a skill that is fundamentally overwhelming and destructive. The power operates on the principle of turning reality into "fiction" or a "lie," effectively removing its existence from the universe. If Kumagawa uses All Fiction on a wound, the wound never existed in the first place. If he uses it on a person, that person never existed.

The Difference Between Deletion and Denial

A crucial distinction makes All Fiction unique: it does not "erase" something in the traditional sense; it makes the concept of that thing *never have been real*. This means the ability bypasses conventional defenses that might resist destruction or spatial manipulation. This power is so profound that it was initially thought to be too great to be detected or measured. While Medaka Kurokami, the protagonist, copied the ability using her skill The End, her version has never been shown to have visible results, leaving Kumagawa's version as the definitive and terrifying benchmark.

7 Mind-Bending Facts About All Fiction's True Power

All Fiction is often debated in power-scaling communities because its limits are consistently pushed, leading to what some call a "No Limits Fallacy" (NLF). However, the manga clearly establishes several incredible, reality-defying feats.

1. It Erases Causality (Cause and Effect)

All Fiction is a form of Causality Manipulation. Kumagawa can use it to erase not just an effect, but the *cause* of that effect. For example, he can remove the effect of a wound, making it as if the attack that caused it never happened. This makes any attack against him fundamentally pointless if he can react fast enough to deny the damage.

2. It Manipulates Fundamental Concepts

The ability’s scope extends far beyond physical objects. Kumagawa has demonstrated Conceptual Manipulation, using All Fiction to erase abstract concepts. In one instance, he even erased the *color* from the world. This means he can target the very building blocks of reality, not just the physical manifestation of those blocks.

3. Its Range is Considered Universal

In the ongoing discussions about the power levels within the *Medaka Box* universe, Kumagawa's All Fiction is generally regarded as having a Universal range. This means its potential to deny existence is not limited to a small area but can theoretically affect everything within the known universe.

4. The Limitation is Only His Range

Despite its seemingly infinite power, All Fiction does have a critical limitation: Kumagawa can only use the ability on things that are within his range. While this range is Universal, it still implies a physical or conceptual boundary to his immediate influence, preventing him from simply erasing the entire multiverse with a single thought.

5. It Can Be Used on *Himself*

Kumagawa frequently uses All Fiction on his own body. He can deny his own wounds, making them vanish instantly. More profoundly, he has used it to deny his own death, allowing him to return to existence after being killed. This self-denial makes him virtually immortal, as he can always "deny" the state of being dead.

6. It Created a New Ability: Parasite Seeing

All Fiction's indirect influence is also profound. When Kumagawa blinded Zenkichi Hitoyoshi with All Fiction, the sheer conceptual shock and trauma led to Zenkichi being granted the abnormality "Parasite Seeing" by Ajimu Najimi. This shows that the denial of a fundamental sense can trigger the creation of a new ability, further demonstrating its reality-warping impact.

7. It Led to the Creation of Non-Fiction

Kumagawa’s ultimate evolution of his power is *Non-Fiction*. This ability, which appeared later in the manga, is the opposite of All Fiction: it allows him to turn what is *false* (fiction/lies) into *truth* (reality). This upgrade solidifies his status as a true reality manipulator, capable of both denying and creating existence, making him one of the most formidable entities in the *Medaka Box* world.

The Lasting Legacy of All Fiction in Power Scaling

The discussion around "All Fiction Medaka Box" remains one of the most heated topics in power-scaling forums today. The ability’s conceptual nature—the denial of reality, causality, and abstract concepts—places it in a tier above most conventional superpowers like super strength or energy blasts. Misogi Kumagawa's character, the "Worst" who wields the ultimate "Minus," is a masterful piece of meta-fiction. The fact that he is aware he is in a manga and his power is literally "All Fiction" is a deliberate commentary by the author, Nisio Isin, on the nature of fictional power itself. As the *Medaka Box* series celebrated its 15th Anniversary recently, the depth and complexity of All Fiction continue to be analyzed by fans. It serves as a benchmark for conceptual power, forcing debaters to consider what happens when a character can simply say, "That never happened," and have the universe agree. All Fiction is not just a skill; it is a narrative device that fundamentally breaks the rules of its own world, ensuring its place in the pantheon of overpowered anime abilities for years to come.
