Right, I'm pretty new to this whole approval stuff, so Animus'll correct me if I'm wrong, but there's a few things you need to edit here.
First, please name your sword. It doesn't take much time to think up a name and it makes it that bit more personal. I mean, every owner names their sword. It's like a puppy...but you can kill people with it.
The rank seems fine to me, but I think the rank of your weapon'll depend on what level jutsu you want to use out of it. At the moment, you can only use the most basic fire techniques, so I'd bump it up to B rank.
A little bit of description in the appearance would be nice, you could put the picture in img code too, all you gotta do is type
with no spaces, and untick all the boxes at the bottom of the page.
Aside from that, I can't see anything else wrong.
