"Not even Magic can escape the bonds of Logic." — Himiko Kudou
Houjutsu (法術, lit. “Law Technique” or “Art of Logic”) is a metaphysical power system featured in the GetBackers universe. It is the ability to manipulate, rewrite, and control the fundamental laws of reality through superior logic. Unlike magic, ki, or psychic power, Houjutsu operates at an existential level, allowing its users to impose higher-order logic structures that override the very fabric of being.
Overview[]
- Name: Houjutsu (法術)
- Translation: Law Technique / Logic Art
- Type: Metaphysical Reality Manipulation
- Users: Ban Mido, Der Kaiser, Kuroudo Akabane
- Debut: GetBackers (Infinity Fortress arc)
Description[]
Houjutsu is not bound by traditional notions of energy or physical prowess. It operates on the principle that reality is built upon conceptual "logic lines"—abstract, invisible structures that define existence, causality, and hierarchy. By perceiving and manipulating these logic lines, Houjutsu users can restructure reality according to their will.
In combat, Houjutsu is less about force and more about the dominance of logical frameworks. A user’s success hinges on whether their logic supersedes the opponent’s.
Core Principles[]
| Principle | Explanation |
|---|---|
| Logic Dominance | The stronger or "higher" logic will overwrite the "lower" or weaker logic. |
| Reality is Code | Reality behaves like a program or equation—Houjutsu rewrites it. |
| Existential Warfare | Battles are not of strength, but of metaphysical correctness. |
| Hierarchy of Truths | The Infinity Fortress itself is layered by logic tiers—from low to divine. |
Abilities[]
Reality Overwriting[]
Houjutsu can erase an object, concept, or being if their logic is inferior. This is not metaphorical—it literally nullifies their reason to exist.
Conceptual Erasure[]
By asserting a superior logic line, a user can destroy intangible phenomena like curses, souls, or alternate timelines.
Logic Substitution[]
A user may not destroy but instead substitute a different logic to replace an existing one. This could neutralize powers, redirect outcomes, or reshape environments.
Known Techniques & Users[]
Ban Mido[]
- Verschwinde Geist: Nullifies an enemy’s existence by imposing a superior logic equation—used against logic-souled entities.
- Reality Banishment: In theory, Ban could erase reality itself by applying an all-encompassing logical override.
Kuroudo Akabane (Dr. Jackal)[]
- Dominant Assertion: Uses the logic “The low cannot stand against the high” to nullify entities in Beltline supported by lesser logic.
- Reality Pierce: Uses blades as conceptual vectors to break through layers of logic shielding.
Der Kaiser[]
- Supreme Logic Rewrite: Considered the most powerful Houjutsu user. He can reshape logic universally with zero resistance.
The Logic of Infinity Fortress[]
The Infinity Fortress is a tiered world built on stacked layers of logic:
- Lower Levels: Governed by conventional cause-effect rules and limited logic structures.
- Beltline: Mid-tier region where logic manipulation becomes possible.
- Babylon City: Top of the Fortress—home to the highest forms of logic and beings like Der Kaiser.
Rule of the Fortress:
“The low cannot stand against the high.” This foundational axiom governs all interactions.
Weaknesses[]
| Limitation | Description |
|---|---|
| Logic Clash | If an opponent’s logic is superior or more complete, Houjutsu fails. |
| Conceptual Blind Spots | Failure to perceive key logic lines can lead to being outmaneuvered. |
| Mental Strain | Rewriting reality requires clarity, willpower, and high cognition. |
Trivia[]
- The kanji 法術 is shared with other series, but its meaning in GetBackers is uniquely metaphysical.
- Houjutsu can be interpreted as a kind of “narrative manipulation”—the user becomes the author of reality’s script.
- Der Kaiser’s Houjutsu is so potent that it is rumored he could undo existence itself, yet chooses restraint.
