Seal Of Slaughter

The moment Klaus heard the name of the red rune, he knew it wasn't something friendly. He wasn't foolish enough to think anything called "Slaughter" was about rainbows and sunshine. He could tell this was dark, and the Senior's next words confirmed his suspicions.

"Brat, this Seal came from the Pentaface Bead when you activated the Nine Stars Blood Moon Transformation. I hope I don't need to explain what that means—you should know not to take this lightly," the Senior said firmly.

"I figured, Senior, but what exactly does it do? More importantly, what is the Seal of Slaughter?" Klaus asked, curious despite the unsettling vibe inside the soul sea.

The Senior chuckled. "Well, brat, you're one lucky bastard."

"Language, Senior! And why is this thing lucky? From where I'm standing, it looks more like a walking disaster," Klaus replied, feeling a mix of excitement and doubt. The rune was practically seething with bloodlust, which didn't sit well with him.
