A sword made by Densetsu

I AM THE STORM THAT IS APPROACHING!

No sword will be ever as strong as the Sword of Faith, at least not the same power

In the sword of faith's universe the you are right

In any other universes then you are wrong

Not universe, reality, if the sword would go in your reality, it would probably gain more or less power depending on that realities laws

Cant, with its magical Obsidian core, it is resistant to class A magic

*Banishes it using reality ruby*

It is resistant to class A magic, banishing in another reality is class A magic, the reality ruby or what ever it is uses class A magic, to banish you can ONLY use class A magic, no higher, no lower

*Bribes limitless Devourer to break Sword of faith*

It is made of a diamond alloy, fused with magic, it is resistant to class A attacks, to bending and to cracking, this sword if it wasn't for a few limitations would be a Class S sword, but because of the limitations it has, it is a Class A++ Sword

Here's the thing. Limitless Devourer is capable of anything (It doesn't make living beings unexist because that is cheating). The Limitless Devourer doesn't care about the class of the sword. It will break it anyways. The Limitless Devourer doesn't have Limitless in its name for nothing

And the sword of faith isn't called of faith for nothing, i never said it can't be destroyed, because, even if it gets destroyed, it would come back

Welp then I'll just put these following swords in class S
Murasama
Murasame
Kura Tamashi
Universal end
Pearlescent rainbow
Pearlescent Murasama
Exile
LowTierSteel

These following swords in S+
Sword of creation
Gold saber

Welp i never said it was the strongest for power, it's because it has the capability of destroying timelines, resetting them to the point where it appeared, and the fact it cannot be destroyed for ever, it puts it in a little under, so in Class S - -

Those swords are the "strongest" they differentiate in power

Murasama is pure strength
Murasame is strength of will
Kura Tamashi is strength from hatred
Universal end is power from the it's surroundings
Pearlescent rainbow and Pearlescent Murasama draw it's power from the heart
Exile is power from the dark side of the user
LowTierSteel draws it's power from electricity

And the Sword of Faith draws power from well, faith, the higher the user's faith is, this includes determination and motivation, the more powerful the sword is, so from a S, - - to a Class S+
