Suzu Barrier Scale, Arifureta Vol 10/12

Suzu hadn’t just been throwing barriers out willy-nilly.
The number of barriers she’d summoned with her left fan numbered 150.
Furthermore, she’d poured all of her remaining mana to create another 300 barriers to add to the massive barrier burst she was preparing.
All of her shields converged on the copy.

...
Suzu didn’t even wait for her to finish before chanting, “Enclose them all, great barrier of isolation. Bring forth a dimension of unending desolation. Heed my call, inescapable cradle of death—Hallowed Ground - Shrine of Oblivion!”
That was the longest incantation Suzu had recited yet.
Orange mana spread out radially around her, covering everything up to a kilometer out and two kilometers above her.
Then, a huge, cylindrical barrier shimmered into existence at the edges of her mana burst.
All of the monsters Eri had summoned were encased within it.
Only Inaba—who’d known what was coming—had managed to escape the barrier’s reach.
