Rimuru brought the two of them to Tony.
"When you see Tony, just don't beat him to death. We've got recovery potions, so he's guaranteed to live."
The two nodded, feeling both nervous and ill at ease, yet eager to kill their enemy with their own hands.
"Tony, come quick! I brought your creditors!" Rimuru called excitedly as he found Tony. He couldn't wait to see him get beaten up. What goes around really does come around.
"What creditors? How could I, Tony Stark, owe anyone anything?" Tony walked out looking puzzled and came face-to-face with Rimuru, Wanda, and Pietro.
But the perceptive Tony immediately sensed that something was wrong. The atmosphere, the way the two children looked at him, and the wicked grin on Rimuru's face made him feel as though a huge "Danger!" had appeared above his head.
"Uh, I've got something to do, so I'll be going..."
Before Tony could finish, Pietro sprang forward and knocked him down with a sliding tackle.
"Tony, you might as well stop struggling. These two kids have the same background as you. Their parents were taken from them by bombs made by Stark Industries. Look, I didn't stop you from avenging your parents, and I certainly won't stop them from avenging theirs. Don't worry, there are plenty of recovery potions."
Rimuru tried to reassure Tony, but anyone could hear the gloating in his voice.
Tony understood where the two children came from and why they were here, but he still wanted to make one last attempt. "Could you not hit my face?"
Soon, Tony's screams rang out. Rimuru thoughtfully closed the door and put up several layers of barriers around the room to keep Wanda from tearing the place apart.
He crouched to one side and watched the two beat Tony,
