Deciphering Kohonese texts

[lala]

There are a few spots with some text written in what is probably Kohonese.
I was wondering what it said, so I tried to decipher it.
I didn't have much to go on, until I noticed a little word in Koho, which obviously says "Koho":

Next, there is a giant slab with text in Springleaf Path:

This one says:
"Blessed be those marked by death".

Now, if I didn't miss anything, the last one is in Fairy Springs:

Except, there is now another language here, that is not seen anywhere else.
The smaller stone to the left reads:
"Fairy commander Ishii forever to be remembered".
The big one in the middle, I have no clue. Maybe someone else here could help with it.

I went through the entire game to make sure there aren't any texts I forgot about and haven't found any, but if I did miss something please correct me.

Now here's a chart of the letters I deciphered:

Lastly, after doing all this, I snooped around in the game files and found the entire Kohonese alphabet in order. I didn't want to look as it ruins the fun of deciphering it myself, but if anyone is interested in seeing it, know it's in there.

there is one more where you did the input combination for the fool sigil.
It says: "The fool will dance as follows"

Right, this gives us W.
I also realised Melilot's tent has some text on it which probably reads "M. Go", for "Merry go", her exploration team:

So we got G as well.
But now I'm wondering, if this alphabet is also used in Karst, is it really called Kohonese?
