So, I started to dive a little deeper in Endless lore, and, while digging into Hissho lore, decided to decipher text on Hokyu blade (btw, is this blade just named after Clan manufacturer in comic or it's an official naming for it?).
From what I can see, the comic shows only this part:
"will be so until the stars turn dark and the last hissho falls
the blade is a responsibility, a gift from the sun god, Tonatsi."

It can be seen on this 2 pages:

I have turned them, as text at the bottom was upside down. As we can't see any other parts of the blade, my question is-does anyone know other parts of the oath? Or if anywhere else I can see it? I only found out, that intro cinematic has seemingly full writings, but it's hard to differentiate symbols in low quality. I could only understand the phrase "enemy's blood or offer(ing?)" from under the hand, but nothing further.

Also, wanted to add-why does CGI blade filling empty space between words with "a"? Looks a bit silly​

That's Fomorian scream in the background, while warrior narrates the oath.

Hello, everyone. I am new here.
