The dark katana,Tojis ultimate weapon.

So,what do you guys think?How powerful should it be?I figured powerful enough to slice through entire buildings,but I want you opinions on weather that would be to Bleach-like.

That does sound awesome but it also sounds too powerful. I'm not sure, what's the story behind Toji's Katana?

Well,I wished to unveil it during the main stream,buy...It's the blade of the Okami Clan ,and the one who holds it shall be the Cheif,it is foretold.It is said to be made of a archdemons soul,and he who holds it has to be as powerful as a Demi-God,or is to be in the future,anyway.Suffice to say,the Clan won't be happy when they find put a good half demon has a hold of it.

Yeah having the blade cut through a building because it is possessed by an Arch-demon as powerful as a demi-god makes sense.

Well,it's jot possessed,per say.It's actually made of a archdemons soul,but why,that's pretty much the way it is.

I don't think it should be able to cut through a building unless it is the length of a building (which is very unlikely). Although windcutter techniques (cutting the air with a sword to attack things at a distance) can work very effectively in anime, I usually have a problem with it. If you can cut things at a distance, then the value of the sword really goes down because it really isn't the actual blade that is doing the cutting.

Some swords turn their wielders' into expert swordsman by gifting knowledge of swordsmanship. In Toji's case, that wouldn't work. His blade is (in my understanding) a physical manifestation of his or someone else's spirit. No old sword sage ever infused the blade with knowledge. But you know your character better, so if this works for him, then go for it.

Some swords can cut through anything (and I mean anything), but only as far as the blade reaches. Force-fields, stone, diamonds, laser, magic.

Also, if it's the dark katana, then it could possibly be used to alter the arena. It could drain all the light out of a certain zone, leaving two or three people alone in a sort of shadow-realm. All this would accomplish would be to avoid collateral damage, and force the oppnent to fight Toji one-on-one.

Yah,I like that better Grace.Able to cut through anything,and able to put two or three people into a sort of shadow realm.
