Abel stared at the tall, shadowy figure of the Emperor of Nothing, and inside his black hood, he didn't see Arad's face, but Agnar's face, hidden with void magic. Inside that massive coat, it wasn't Arad, but four different people.
Yuwaku stood up, and Agnar sat on her shoulders with Ignis and Theresa on her arms, the four of them fully forming a huge, bulky body that somewhat matched that of Arad. Thanks to Yuwaku's void magic and a few illusion tricks from Merlin, they could easily shift her aura to feel denser and more threatening than it really is.
Granted, Yuwaku herself was threatening enough, but clearly nowhere near the rabid madness Arad could cause.
