Masadaverse, is a series of visual novels written and done by Takashi Masada. All the novels that are part of the verse include: Paradise Lost, Dies Irae - Interview with Kaziklu Bey, Dies Irae - Amantes Amentes, Kajiri Kamui Kagura, and Avesta of Black and White.
Shinza Bansho is a very powerful verse and easily one of the strongest in fiction.
In Paradise Lost, the strongest characters have feats of dragging continents into the Abyss, controlling the atmosphere and manipulating it, and even destroying a mini-star with power and density of an actual one. However, with Quintessence they are capable of affecting higher dimensions (these higher dimensions scale to Taikyoku values and therefore serve as aleph layers) to the point where one character (Lyle) is capable of killing God (Muzan). Their speed is also impressive being Massively Hypersonic+ with Speed of Light Reaction speed.
With Dies Irae, the verse's power increases drastically. Most characters can now destroy and vaporize cities to mountains (beings can effortlessly tank the Tsar Bomba, and characters that can split entire mountain ranges), with a few continent level beings and some planet level entities as well. However, once Hadou Gods are introduced the verse's power skyrockets to Boundless with characters transcending any and all possible hierarchies of Creation and the Singularity including all concepts like time, space, dimensions, physics, metaphysics, duality, non-dualism, etc. The speed is also very impressive with characters easily being thousands of times mach speed (Only applies to the average characters)
Kajiri Kamui Kagura increases their power even further, once again including several powerful Mountain to Universal beings with Hypersonic+ speed as well as more Boundless entities (As well as one infinitely beyond all others
