Kny Special One Shot - Blog Posts

Is there anyone here who learns Japanese and read KNY cause I have some questions about the special one shot with Kyoujuro

It is said that thanks to his friend's fingers characters, Kyoujuro managed to figure out the demon's power. These are scenes where their hands are shown, and I am quite curious on how to read the signals.

What do they actually say? Even though they're fragmented information, is there secret coding in the corps that slayers use for each other in exchanging secret information? Do the characters formed by their hands worded out something like 'flutes' or 'nerves'?

I am not sure if there's anything in the manga that said there's a secret coding language between the slayers, but it'd be cool and useful if they have the system.
