Tony Stark walked out of his office with two enormous dark circles under his eyes.
He might have been arrogant and conceited, but his mind was exceptionally sharp.
After a brief exchange with Rimuru, he had already gotten a fairly thorough grasp of Rimuru's Wind God. The emergence of the new-element reactor, in particular, had been a real eye-opener for Tony Stark.
