Merlin

This was getting interesting. The Demon formed a broad grin on his face as he locked eyes with Kristoph. He pushed the man's fist away one more time, just this once while using Air magic as support.

"You know, I didn't plan on using magic during this fight. But since you're using your benefits as a 'Letter', we can't call this unfair, can we?" Eiro asked, and Kristoph immediately froze, "How do you-"

"Exactly, how do I know? Ask yourself that question, bud. Now, which Letter are you? B? Maybe even A?" Eiro just stood there, basically pausing this duel for now as Kristoph looked back at him with a nervous glare, "I don't see how that's any of your business."

"Oh, but it certainly is~... After all, I'll need to face you during my conquest of the organization anyway." The Demon whispered, just loud enough so that Kristoph could hear it. The man in front of Eiro ripped his eyes open wide as he heard these words.
