Explaining the destruction Deus verse and Tiering system

This should clear y'all doubts about this Alternate version of the Dxd universe

The Destruction Deus verse I an alternate version of the dxd universe in which There was a 3rd dragon God this Dragon's name is Bahamut the dragon God of destruction and death

Bahamut was the strongest existence in this verse strong enough to destroy the Multiverse but because of boredom he decided to live his life as a mortal and making it so that his power will chose a worthy wielder from his bloodline which he had after becoming a mortal and having children

That's where Issei comes in Issei is the descendent of Bahamut and has Bahamut's power sealed inside him making him much stronger than his cannon counterpart in this AU Issei is much more Handsome isn't a perverted Idiot and he basically at the peak of humanity before unlocking his bloodline and sacred gears

Issei did not become a devil in this universe instead he was good friends with the ORC and the Student Council

Issei unlocked his dragonic powers after getting to know about the supernatural after getting attacked by Raynare and making her flee and after that he still met Asia and most things happened as Cannon but after Asia sacred gear was removed Issei unlocked both the boosted gear and Philosopher touch sacred gears and killed Raynare after beating her up and making her explode from the inside out by using one of Philosopher's touch's ability called restructure (Basically Overhaul)

As time continued Rias engagement with riser was revealed and issei fought riser for Rias hand in marriage and won by using balance breaker

The destruction Deus verse is basically Dxd with a better issei that had much more power and new forms due to his heritage of dragon God

The power levels are different as well for example

Hades: 5-C (moon level)

Sirzechs, micheal and Azazel: low 5-B (small planet level)

Shiva:4-B (solar system level)

Trihexa: 4-A(multi solar system level)

Gread red and ophis: 3-C(galaxy level)

Trihexa 666 from another dimension:low 2-C (universal+)

Bahamut: high 1-C (High complex Multiversal)

The trihexa from another dimension is a version of 666 that managed to destroy everything in it's universe and due the the chaos it gained more power and so it travels into other dimensions to cause chaos and gain more power

The fight with this trihexa will be after a long time in my story it will atleast be after the Mc has gone to many more dimensions

If y'all know about the Tiering system don't read this

Tiering System

Tier 10: Human

10-C: Below Average Human level

Characters capable of exerting force comparable to humans who are below the average norm in terms of strength, such as small children or infirm people, as well smaller animals such as cats and dogs

10-B: Human level

Tier 9: Superhuman

9-C: Street level

Characters who stand at the threshold of human strength and capabilities, represented by olympic level athletes or rigorously trained martial artists, as well as larger animals.

It is important to note that, despite being named "Street level", this tier has nothing to do with actually affecting an entire street, with the name being moreso a reference to street fighters as portrayed in martial arts movies and the like.

Tier 3: Cosmic

This tier is broken into the following sub-tiers:

3-C: Galaxy level

Characters capable of creating and/or destroy a galaxy, when the space between celestial bodies is taken into account, as opposed to simply the matter encompassed by them.

3-B: Multi-Galaxy level

3-A: Universe level

Characters who can affect/create/destroy a finitely sized universe. This is usually exhibited through explosions/implosions, omnidirectional energy blast, or a shockwave that encompasses all of the stars and planets within a universe.

High 3-A: High Universe level

Characters who demonstrate an infinite amount of energy on a 3-D scale, or those who can affect an infinite 3-D area or an infinite number of finite or infinite universes when not accounting for any higher dimensions or time, or more generally any area of comparable size. Large numbers of infinite universes, unless causally closed from one another by a separate spacetime or existence, only count for a higher level of this tier. Being "infinitely" stronger than this level, unless uncountably so, does not qualify for any higher tier.

Tier 2: Multiversal

2-C: Low Multiverse level

This tier is broken into the following sub-tiers:

Low 2-C | Universe level+: Characters who are capable of significantly affecting, creating and/or destroying an area of space that is qualitatively larger than an infinitely sized 3-dimensional expanse. Common fictional examples of spaces representing such sizes are space-time continua of an universal scale, though it can be more generally fulfilled by any 4-dimensional space that is either:

A) Provably infinite, one which can be safely assumed to be so, or that is of an otherwise non insignificant size.

B) Portrayed as infinitely larger than lower-dimensional objects and spaces in the setting of a given work of fiction.

C) Equivalent to an extra dimensional space.

2-C | Low Multiverse level: Characters who can create and/or destroy small multiverses which can be comprised of a number of isolated space-time continua ranging anywhere from two to a thousand, or equivalents.

2-B: Multiverse level

Characters who can create and/or destroy larger multiverses which comprise from 1001 to any higher finite amount of isolated space-time continua.

2-A: Multiverse level+

Characters who are capable of affecting, creating and/or destroying a countably infinite number of spatio-temporally isolated universes.

Tier 1: Extradimensional

Characters who can significantly affect spaces of qualitatively greater sizes than ordinary universal models and spaces, usually represented in fiction by higher planes or levels of existence which trivialize everything below them into insignificance, either by perceiving them as akin to fictional constructs or having a size equivalent to a greater infinity in relation to them.

This tier is broken into the following categories:

1-C: Complex Multiverse level

Low 1-C | Low Complex Multiverse level: Characters who can affect, create and/or destroy the entirety of spaces whose size corresponds to one to two higher levels of infinity greater than a standard universal model (Low 2-C structures, in plain english).

This rating can be reached by 5 and 6-dimensional constructs and spaces when they are either of an infinite (or otherwise non-insignificant) size or portrayed as qualitatively greater than lower-dimensional objects in their setting, or alternatively, one can also qualify for its lower end by creating and/or destroying an uncountably infinite number of universes, or more generally, showcasing uncountably infinite power/size when compared to 4-D beings or objects.

1-C | Complex Multiverse level: Characters who can universally affect, create and/or destroy spaces whose size corresponds to three to five higher levels of infinity greater than a standard universal model. In terms of "dimensional" size, this can be equated to 7 and 9-dimensional real coordinate spaces (R ^ 7 to R ^ 9)

High 1-C | High Complex Multiverse level: Characters who can universally affect, create and/or destroy spaces whose size corresponds to six to seven higher levels of infinity greater than a standard universal model. In terms of "dimensional" size, this can be equated to 10 and 11-dimensional real coordinate spaces (R ^ 10 to R ^ 11)

1-B: Hyperverse level

1-B | Hyperverse level: Characters who can universally affect, create and/or destroy spaces whose size corresponds from 8 to any higher finite number of levels of infinity above a standard universal model. In terms of "dimensional" size, this can be equated to 12-dimensional real coordinate spaces and up (R ^ 12 and up)

High 1-B | High Hyperverse level: Characters who can universally affect, create and/or destroy structures whose size is equivalent to a countably infinite number of qualitative sizes above a universal model, usually represented in fiction by endless hierarchies of layers of existence, each succeeding one completely trivializing the previous into insignificance.

Infinite-dimensional spaces and objects can qualify for this tier if they are either provably infinite in all of their axes. or can be safely assumed to be so, while characters who only encompass finitely-sized subsets of each axis of infinite-dimensional space are defaulted to High 3-A.

1-A: Outerverse level

Characters who functionally transcend the rest of the Tiering System, and stand outside of any extensions of infinite hierarchies and sizes, to varying degrees and magnitudes. In more straightforward terms, this category could be said to be occupied by characters whose size and/or level of power cannot be reached by merely stacking bigger infinities ontop of each other.

Low 1-A | Low Outerverse level: Characters who can universally affect, create and/or destroy structures and expanses of uncountably infinite dimensions, or which have a size roughly analogous to them, such as uncountably infinite sets of hierarchical layers or planes of existence, most specifically ones whose amount of layers is comparable to the set of all real numbers, and are thus equated to the first uncountably infinite cardinal, ℵ1, for simplicity's sake.

Alternatively, this tier can also be assigned to characters who transcend High 1-B structures when no further context regarding the nature or such transcendence is given.

1-A | Outerverse level: Characters who can significantly affect, create and/or destroy realms or states that fully transcend infinitely-layered hierarchies and/or dimensional levels on a conceptual or existential level, normally being portrayed as completely external abstractions that lie outside of the applications of spatiotemporal dimensionality as a constant defined by physics on any level, even in relation to infinite or uncountably infinite dimensions, usually by perceiving them as akin to fiction or something similarly insignificant.

However, do note that it is possible for a character to qualify for this rating even if their verse does not have an infinitely-layered or equivalent cosmology, as long as it is either stated, shown or left very obvious that the character in question already bypasses the very nature of such structures altogether, in a way that simply "stacking" more of them logically would not allow one to reach their level of power / size. [1]

Mathematically, 1-A has its size represented by further uncountably infinite cardinals beyond useful applications of certain measures (ℵ2 and onwards, most specifically) and can be extended unto greater levels of infinity, representing different complexities or qualitative "steps" on an Outerversal scale, in the same way 1-B and 1-C are divided. Characters who stand an infinite number of steps above "Baseline" Outerversal realms and structures are to have a + modifier in their Attack Potency section (Outerverse level+)

High 1-A | High Outerverse level: Characters who can affect and create/destroy states or realms which are completely transcendent over infinitely-layered Outerversal hierarchies and any extensions thereof, as well as the framework in which such entities are defined in the first place. Note that simply adding more "layers" to an already infinite 1-A hierarchy (or some structure of equivalent size) is not enough to reach this tier, and one must be completely external and unreachable by it in any form.

Tier 0: Boundless

0 | Boundless level: Characters who demonstrate an equivalence to, or can create/destroy/affect, transcendental abstract levels of existence which conceptually stand superior to even High 1-A levels. Being "omnipotent" or any similar reasoning [2] is not nearly enough to reach this tier; characters at this level must transcend High 1-A characters as High 1-A characters would transcend 1-A ones. This tier has no true endpoint, and can be extended unto any higher level, spiraling infinitely upwards
