Shinza Banshou, also known as the Masadaverse and previously called Kami-Sama Series, is a series of visual novels written and done by Takashi Masada. There are a total of four main entries written by him: Paradise Lost, Dies Irae, Kajiri Kamui Kagura and Avesta of Black and White, with the additions of the spin-off Dies Irae-Interview with Kaziklu Bey and the currently unreleased Dies Irae: PANTHEON. The four main entries, plus "IKaBey" (a canon prequel to the main storyline of Dies Irae), Song to the Witch (another story that takes place after DI's prologue but before its main story) and the mobile game PANTHEON that takes place after Kajiri Kamui Kagura, follow the battle for the Throne across aeons.

Forced to wield the same unholy power as his foes, will Ren be able to protect what is dear to him from the inhuman might of the Longinus Dreizehn Orden?
Kajiri Kamui Kagura
In ancient Ashihara no Nakatsukuni, generals fought each other to gain the favor of the emperor. They attempted to invade the uncharted eastern lands, but suffered total defeat at the hands of demons more intelligent than humans. Three hundred years later, the land of the gods, Shinshuu, has locked itself away from all foreign countries, but an air of gloom begins to drift in from the east. They are forced to head east again to drive away the demons.
Avesta of Black and White
Power of the Verse
As a whole, Shinza Banshou is an extremely powerful franchise and some of the strongest visual novels.
In Paradise Lost, the strongest characters have feats such as dragging all of the continents into the Abyss, controlling the entire atmosphere and manipulating it at will, and creating and destroying a miniature star with power and density comparable to the actual one. However, in speed they're very subpar, capping out at Subsonic with Supersonic+ reactions.
With Dies Irae, the verse's power increases astronomically. Most characters reach from City level+ to to all the way to Mountain level (Being able to harm beings who can completely tank the Tsar Bomba, and superior to characters who can bust entire mountain ranges), with a single Continent level being and a Planet level entity. However, with the introduction of the Hadou Gods, their power skyrockets to Outerverse level and above, having transcended duality and all binary concepts. In terms of speed, it's fairly impressive, with most of the cast boasting quadruple-digit Mach speed.
Kajiri Kamui Kagura increases their power even further, once again including several City level+ to Mountain level characters plus another single Planet level entity with Massively Hypersonic+ speed and even more Outverversal entities (Including one infinitely beyond all the others).
However, where Shinza Banshou truly shines is their hax capabilities, with even low-tiers having some form of Reality Warping or Soul Manipulation, and others having abilities such as the trait of always being faster than one's opponents, regardless of whether or not they are beyond the concepts of speed, distance, time, or space, erasing the existence of their enemies with one punch as long as they have a history, attacks that never miss their targets no matter what, stopping time in a space where time does not exist (and is powerful enough to affect Outerversal abilities), Causality Manipulation, Cutting through space and time, ignoring Resistances, Conceptual Manipulation, and many more.
Die Ewigkeit: A magic formula created by the Hadou God Mercurius, which allows the user to absorb souls and convert them into power. The basic abilities of all Die Ewigkeit users include: The ability to absorb the souls of the dead and boost their power with it (With merely 1,000 souls, nuclear weapons are completely ineffective), the ability to sense souls over very large distances, and detect their individual characteristics, have a body that only serves for physical interaction (Even if their entire body is destroyed, they will regenerate as long as their soul is intact), have power derived from a "Holy Relic" (Which can be any item of the user's choosing), and the ability to deal spiritual damage in conjunction with physical.
Assiah: The first level of the Die Ewigkeit formula, the characteristic that indicates the Holy Relic has merged with the user’s soul. At this rank it is incorporeal and somewhat unstable while at the same time giving the user a strong desire to kill. It also grants a more resilient body but can still be killed by hitting vital areas like the heart. What a Holy Relic does varies from individual to individual.
Yetzirah: The second level of the Die Ewigkeit formula, when the Holy Relic gets a physical form and the user is finally starting to show their particular traits. The Holy Relic can now said to be finally stable and can be weaponized (Wilhelm turning the blood of Vlad the Impaler into spikes, for instance). His or her body is now strengthened to superhuman levels and the body will stop aging, although the soul will continue to do so.
Briah: The third level of the Die Ewigkeit formula, which allow's the user's absolute deepest desire to be made reality. There are two different types of Briah, Hadou (Which is when one's desire focuses on others) and Gudou (When one's desire focuses on themselves). Said desire gives the user an ability relating to it in at least some capacity (Schreiber, for instance, has the desire of "I do not want to be touched by anyone", and his Briah manifests as an ability that lets him always outspeed his enemy no matter what they attempt outside of outright time stop). When the user has a Hadou desire, their ability will alter their surroundings, while a Gudou desire will alter themselves, though mixtures of both do exist (Such as with Wilhelm).
Atziluth: The final and ultimate level of the Die Ewigkeit formula, when the user becomes a full-blown God and starts to paint over reality with their own Law, essentially making the universe/multiverse a canvas. The ability given to one by their desire is now amplified to far greater levels (Schreiber being able to bypass the very concept of speed to go faster than his enemy), and users are capable of manipulating reality on a conceptual level, in addition to literally being walking universes, a mere drop of their blood weighing more than a neutron star. The difference of Hadou and Gudou still exists, now in the form of Hadou and Gudou Gods. However, not everyone is capable of attaining Atziluth, as it is a right determined at one's birth.
Taikyoku: The source of power for Atziluth users, Taikyoku is the source of all reality, including dimensional space itself. Taikyoku is generally measured in units, and having more Taikyoku than another Hadou/Gudou God indicates superiority, with having one value more makes it impossible for the weaker Atziluth user to harm you. The most Taikyoku an Atziluth user is shown to have is 100 (However, Hajun possesses infinite Taikyoku due to the odd nature of his existence).
In Dies Irae, there exists an artifact called “the Throne”, an object that has been described as “hyperdimensional” (Meaning above dimensional structures in this context) twice.
「Ab Ovo Usque Ad Mala」
He began to sing the language of the different dimension again. The ancient language of the Outer Universe/Space overflowing from the jarring Hyperdimensional Throne.
No longer can anyone know the works of “Predecessor” anymore because of the Emanation of Mercury.
「Omnia Fert Aetas」
That is place is none other than the Taikyoku Throne. The Nucleus of the Universe, the Center where all phenomena emanated from the existing Law.
Of course that is not the place where one can reach by walking and flying. It is some sort of Hyperdimensional Space, an extreme point that cannot be described by any language.
To even the weakest Hadou/Gudou God, the Throne is nothing more than a tool to use, in addition to being able to both affect and even outright destroy it.
Additionally, the force of “Taikyoku” (Which all Hadou/Gudou Gods use as their power source) is responsible for the existence of all reality, including dimensional space itself.
Furthermore, within the Hyperdimensional Space of the Throne, the concept of time itself does not exist in any manner.
