Casio opened the letter and quickly scanned it.
Regrettably, he couldn't understand a single word.
On the surface of the light yellow paper, rows of black, twisted characters were huddled together. It didn't look like any language, it was more like a cryptogram. Its continuous form and length were similar to some doctors' signatures on hospital prescriptions.
"What the hell is this? A language amongst dark creatures?" Casio turned the paper back and forth with his blood-stained hand.
Indeed, it was a common letter.
But he didn't think it was that simple. After all, the letter was personally placed by the vampire leader, and the contents of the letter likely contained quite a few secrets. However, the language on the letter is obviously a kind that was understandable only by dark creatures, or a language only the Blood Clan could understand.
It was a natural form of secrecy.
The best way to decipher it would be to capture another member of the Blood Clan!
