Of the original 7 members present, 2 of them had died, exactly Katsuo and Yato. Their deaths had arrived so suddenly that the others weren't able to react in time. Even if they could, it wasn't like they wouldn't. The monster was obviously far stronger than the 7 of them combined.; facing it was beyond suicidal.

"Spread out!"
