After arriving here, they naturally had heard about Reiger.
He is one of the five major Special Grade Curse Mages of the modern era, his strength surpassing even Okkotsu Yuta and Tsukumo Yuki, reportedly capable of standing against the most powerful contemporary Curse Mage, Gojo Satoru.
He can use various curses and once defeated Ryomensukuna, who had temporarily gained control over Itadori Yuji's body, during the Shibuya incident.
This is indeed an astounding achievement.
At least, as far as Angel knew, in her lifetime during the Heian period, no one had ever accomplished such a feat.
Ryomensukuna, during the curse's golden age in the Heian period, gathered the most elite team of Curse Mages of that time. Despite mobilizing nearly all elite forces, they were ultimately completely annihilated by him, a mobile natural disaster.
He was no longer regarded as human, nor as a Curse Spirit, but as a calamity.
