The Octagram hall fell into a rare, expectant silence after Rimuru's proposal.
Guy Crimson gave a slow nod. "Very well. Summon him."
The other Demon Lords murmured in agreement, curiosity burning in their eyes.
Rimuru smiled faintly and raised his hand. A small magic circle appeared in the air in front of him. With a calm voice, he spoke a single name:
"Diablo."
A wave of overwhelming dark energy surged into the hall. Black and crimson mist swirled together, forming a tall, elegant figure in a perfect butler suit. The moment he fully materialized, an aura of absolute power and refined danger filled the entire room.
Diablo bowed deeply and gracefully toward Rimuru, his voice smooth and filled with absolute loyalty.
"My lord Rimuru. You called for me?"
Shion puffed out her chest proudly beside Rimuru and declared, "It's your time to shine for Lord Rimuru!"
Diablo gave a small, elegant smile. "As you wish."
Ramiris floated up in shock, pointing a tiny finger at him.
"Wait, wait, wait! Rimuru, you mean this guy is Diablo — the Demon God?!"
Rimuru nodded casually. "Yes."
Ramiris let out a dramatic wail and dramatically fell face-first onto the table with a loud thud.
"How is that possible?! I've met him a few times and didn't treat him properly at all!"
Rimuru chuckled. "Of course you did. He was hiding his power even now."
Ramiris lifted her head, eyes wide with panic. "Will he take revenge on me?!"
Rimuru laughed softly. "Of course he will. He is a Primordial Demon, after all."
Diablo's smile turned slightly sharper as he looked at the tiny fairy.
Ramiris yelped and hid behind Rimuru.
Rimuru waved his hand with a grin. "I'm just kidding."
Diablo bowed again, perfectly polite. "Of course I will not. If I wished for revenge, I would have done so a long time ago."
Ramiris peeked out from behind Rimuru, still wary. She suddenly remembered something and turned to another figure standing quietly in the shadows.
"Beretta! Did you know about this?!"
Beretta, the other powerful subordinate of Rimuru, answered calmly and in full detail, explaining everything he knew about Diablo — even from before they were summoned, leaving out no information.
The Octagram watched the entire exchange with varying degrees of amusement, shock, and interest.
The arrival of Diablo — a true Demon God serving under Rimuru — had just made the meeting far more complicated and intriguing than anyone had expected
