Since coming to this world, Reiger has met quite a number of people, and even more curse spirits, but truly, the only existence that could compare to the Ryomensukuna before him is probably Gojo Satoru.
As for the other special-grade curse mages and Mahito, the special-grade curse spirits like Luohu?
They wouldn't even come close.
The aura he initially sensed was correct, Ryomensukuna is definitely a being that only falls short of human evil and the Monster King.
And yet, even at that, he hasn't fully regained all his strength from his prime.
If he could regain the power of his prime, even Gojo Satoru might not match him.
"It's a pity, from the moment I arrived in this world, you were no longer the strongest."
As he spoke, Reiger made a hand seal, and the shadow beneath his feet began to writhe.
From the shadow, a massive figure slowly emerged and appeared by Reiger's side.
"[Guanniu]."
Reiger summoned a cow-type shikigami of astonishing size.
