{{Quote|
"The depth of the world is the strength of the world's order. It is the amount of influence that the small world has on the Silver Water Holy Sea. Magic power flows from the shallow layers to the deep, and order exerts its power from the shallow to the deep."

== Introduction: The Macro-Cosmological Framework ==

The cosmology of Maou Gakuin no Futekigousha is centered around a transfinite, higher-dimensional structure known as the Silver Water Holy Sea (銀水聖海, Ginsui Seikai), or simply the Silver Sea.

Unlike standard multiverses that simply contain a collection of parallel timelines, the Silver Sea operates on a strict hierarchical and ontological stratification. It is a massive body of "silver water" that contains an endless number of Bubble Worlds (小世界, Shōsekai), organized into distinct Layers (層, Sō).

As of the current Light Novel, there are 99 confirmed layers, though the structure is implied to be infinite in scope. Each layer is not merely a spatial coordinate but represents a fundamental increase in the density of magic power, the complexity of physical laws, and the ontological weight of existence.

Within the PABC Framework, this hierarchical layering is evaluated as a Tier 1-C (Finite Higher-Dimensional Structure) cosmology, specifically modeling a 5-dimensional bulk containing 4-dimensional spacetime continuua.

== Section 1: The Micro-Structure - Bubble Worlds ==

Before understanding the ocean, one must understand the droplets. The fundamental unit of the Silver Sea is the Bubble World.

Each bubble world is a completely self-contained universe with its own spacetime continuum, physical laws, and magical concepts. Worlds are described as having "near infinite black skies stretched out in all directions" and are explicitly stated to be endless in size

Inside a single bubble world, time flows linearly, and matter is governed by local logic. However, the inhabitants of these bubble worlds are typically unaware of the existence of the Silver Sea. To them, their universe is everything. As Anos notes, the inhabitants of a shallow bubble world are like "frogs in a well," unable to perceive the vast ocean outside their limited dimension.

The PABC classification for a single bubble world is Tier 3-A (Multiple infinite spatial universes) or Tier 2-C (Low Multiverse level) depending on whether the world contains its own internal multiverse (such as Militia's world containing multiple realms and timelines).

---

== Section 2: The Macro-Structure - The 99 Layers ==

The true scale of the cosmology emerges when examining the relationship between the layers. The Silver Sea is divided into at least 99 layers, with each layer containing countless bubble worlds

The relationship between layers is not spatial; it is qualitative and ontological. The deeper one goes into the Silver Sea, the more "compressed" and dense reality becomes.

2.1. The Law of Dimensional Compression

The Silver Sea operates on a principle of Dimensional Compression. A spell that is capable of destroying an entire universe in the first layer (Layer 1) would not even be able to scratch a pebble in the 21st layer.

This is explicitly stated in the Light Novel:
> "In the shallow layers, a magic that can destroy a world cannot even destroy a single ship in the deeper layers."

This creates a localized hierarchy where the "difference" between Layer 1 and Layer 2 is treated as a dimensional gap. A 3D being cannot interact with a 4D object; similarly, a Layer 1 entity cannot interact with a Layer 2 entity unless they possess an order of magnitude higher magical power.

2.2. The Mathematical Model (PABC System A)

The PABC Forum recognizes this stratification as a 5D structure.

Let \( \mathcal{W}_L \) be the set of all bubble worlds in Layer \( L \).
Let \( D \) be the depth coordinate.
The relationship between the worlds is given by:
\[
\mathcal{W}{L+1} \succ \mathcal{W}L \iff \mathrm{Order}(\mathcal{W}{L+1}) > \mathrm{Order}(\mathcal{W}L)
\]
Where the symbol \( \succ \) denotes ontological and quantitative superiority (the higher layer is infinitely denser and more durable than the lower layer).

Because the Silver Sea contains an infinite number of these 5D layers (or at least 99 confirmed), it is classified as a Tier 1-C (Low Complex Multiverse level) cosmology.

---

== Section 3: The Abyssal World and the 99th Layer ==

At the very bottom of the known Silver Sea lies the Abyssal World (深淵世界, Shin'en Sekai).

It is stated that the Abyssal World has sunk so deeply into the ocean that it is usually impossible to perceive its existence. Even if one reaches the 99th layer, the Abyssal World can barely be seen

The Abyssal World is the domain of the Great Demon King Zinnia Shivaheld, who rules over the 12 worlds of the deep layers. The order of the Abyssal World is so potent that the very concept of "destruction" is altered; it is a realm where the fundamental laws of the shallow worlds completely break down.

In PABC terms, the Abyssal World represents the boundary of the 5D framework. It is the deepest known point of the Silver Sea, where the density of magic and order reaches its absolute limit.

---

== Section 4: Mythological Context - Militia and the Creation Gods ==

The cosmology of the Silver Sea is intrinsically linked to the Goddesses of Creation.

Militia is the Goddess of Creation who created the world of the Maou Gakuin story. However, she is not the only Creator. The Light Novel reveals a lineage of Creator Gods:
> "For 700 million years in Militia's world alone, the world of her mother Erenesia, the world of her mother, the world of her mother's mother, the Creator Gods have recreated this world generation after generation."

This implies that the Silver Sea is populated by countless worlds created by different Creator Gods, each with their own "Divine Eye of Source Creation." Militia herself possesses the ability to create anything from nothing, but even she is bound by the order of the Silver Sea.

This is a crucial point for PABC scaling: The Creator Gods are not omnipotent. They are extremely powerful entities within the 4D framework of their bubble worlds, but they are still subject to the 5D hierarchy of the Silver Sea. They cannot transcend the layers.

== Section 6: Formal Logic - The 5D Structural Proof ==

Let \(\mathcal{S}\) be the Silver Sea.
Let \(\mathcal{L} = \{L1, L2, \dots, L_{99}\}\) be the set of layers.
Let \(\mathcal{W}n\) be the set of bubble worlds in layer \(Ln\).

The dimensional relationship between layers is defined by the function \(D: \mathcal{S} \to \mathbb{R}^5\), which maps every point in the Silver Sea to a 5-dimensional coordinate system (3 spatial, 1 temporal, 1 depth).

For any two layers \(La\) and \(Lb\) where \(a > b\):
\[
\forall wa \in \mathcal{W}a, \forall wb \in \mathcal{W}b, \quad \mathrm{Order}(wa) > \mathrm{Order}(wb)
\]

The difference in order is so vast that a standard 4D attack cannot propagate from \(Lb\) to \(La\).
Let \(E\) be an energy attack. The attenuation of \(E\) as it moves from \(Lb\) to \(La\) is given by:
\[
E(La) = E(Lb) \cdot e^{-\int_{b}^{a} \kappa(z) dz}
\]
Where \(\kappa(z)\) is the "depth attenuation coefficient" of the Silver Sea. For any finite \(E(Lb)\), as \(a \to \infty\), \(E(La) \to 0\).

To affect a deeper layer, the attacker must possess an energy \(E\) that scales exponentially with the depth \(a-b\):
\[
E{\text{required}} \propto \prod{i=b}^{a} \mathcal{O}(L_i)
\]
Where \(\mathcal{O}(Li)\) is the order multiplier of layer \(Li\).

Because the Silver Sea contains 99 layers, and each layer has a separate spacetime continuum, the total structure is a 5D manifold embedded in a higher-dimensional bulk. Thus, the Silver Sea is a Tier 1-C cosmology.

---

== Section 7: Evidence and Quotes ==

Here are the primary quotes establishing the Silver Sea's structure:

Quote 1: The 99 Layers and Infinite Worlds
> "The multiverse (Silver Sea) is comprised of 99+ layers (Each layer possibly having infinite size), with each layer containing countless universes (Worlds), all of which are separate space-time continuums in the shape of bubbles."

Quote 2: Dimensional Compression
> "The depth of the world is the strength of the world's order. It is the amount of influence that the small world has on the Silver Water Holy Sea."

Quote 3: The Abyssal World
> "The Abyssal World has sunk so deeply into this ocean that it is usually impossible to even perceive its existence. It is said that if you reach the ninety-ninth layer, you can barely see it from there."

Quote 4: The Flow of Order
> "Magic power flows from the shallow layers to the deep, and order exerts its power from the shallow to the deep."

---
== Conclusion ==

The Silver Sea is a massive, 5-dimensional multiversal structure containing 99+ layers of infinite bubble universes. It is a Tier 1-C cosmology under the PABC Framework.

While it is one of the most complex and intricate multiverses in modern fiction, it is still fundamentally a quantitative hierarchy. It does not possess the qualitative ontological transcendence required for Tier 1-A or higher. This capping is essential for maintaining the integrity of the PABC tiering system, ensuring that dimensional stacking is not confused with true ontological superiority.
