Pretty sure it's Non Standard.
He says in chapter 0:
"NS means that it's beyond the usual standards."

Looks very similar (bare foot and he says he is non standard) but the person he was up against was a red headed guy, not this dark haired woman.

I don't see the point really...

A nice update that I have seen elsewhere would be a Marker showing the last chapter you read when your on a stories main page.

The 20th Volume?

I thought this was the last chapter...

Yeah.
I think current timeline Leon is fine, I could be wrong though.

The way I heard it the Earl of Sandwich didn't create them so he could work one handed, but so he wouldn't get meat grease on his cards when gambling...

Nah, I think he is digging a well.

The way I read it, Past Life Leon does.

So the next step is a sports endorsement?

Sceond!

Had a feeling that was going to be the case.

You being sarcastic? I didn't see a single female character... :P

I was thinking Katana's Sword from the suicide squad

I really don't see it being a possibility that she came here by herself... She just isn't that stupid.

Cracks are starting to show :P

And now that it actually happened I feel the sharp edge of an axe...

Almost at the point I gave up reading the novel...

I thought she knew last chapter, but now I'm confused...
