Because the two of them were simply too useless!
They had existed in the world for nearly ten thousand years, yet their strength had remained stuck at the Demon Duke realm. In the end, they could only advance to the Demon King realm with Lord Rimuru's intervention!
Although Ultima had also advanced to the Demon King realm through Lord Emperor's blessing, she believed that if she, Raine, and Misari had manifested in the world at the same time, then even if they could not compare to that "freak" Guy, they should still have been stronger than those two!
