"As a Gudou God, it can be said to be the ultimate sword attack. Attack transcending concepts such as speed, skill, exploding the elements that exists between him and his opponent, turning the universe itself into swords that can reach any place, cutting phenomenon impossible to escape, severing the World of Poison, world of Tenma Akuro."
"Soujirou states that whoever fought against him "died". This isn't some kind of physical cutting attack, but something beyond, a higher dimensional form of conceptual cutting. Idea of slashing itself, absolute severance whether it was Tenmas themselves, or even visions of the future. Soujirou only managed to understand this power after becoming a God."
Kajiri Kamui - Kei Tsunushi Futsumitama no ke: Soujirou's Taikyoku, Gudou type, born from his desire "I want to become a blade". Desire to become the strongest swordsman in the world. It's the ultimate destination Soujirou has long sought. But everything would eventually be cut, leaving nothing for the God of the Sword. Eventually, he found a person to love and cut forever, one that desires to receive the gleam of his sword, one in which he desires to reach her core. Ability of this law is "cutting all that exists". From the physical to the metaphysical, tangible or intangible, concrete or abstract, everything is severed. Lifespan, luck, law, soul, distance, time, infinite possibilies, fate, space, dimensions, spirits, All is slashed. While his Taikyoku may seem to be surpassed, it will still affect his targets. First the flesh is severed, then his law goes deeper down to the "core" of everything. Moreover, as this Law turns Soujirou into the "sword" himself, this ability works with anything, even chopsticks or even bare handed will cause a cutting phenomenon. Logic no longer applies to him, so idea that a single swing result in a single slash is nonexistent. There's no concept of swinging, so everthing is hit. Distance doesn't even matter as it is cut too, so his distance infinite.
I think he should be up there with Khorne.
