"Index, what's wrong?"
The girls of ITEM quickly gathered around the silver-haired nun, watching her anxiously.
But aside from pained groans, she could spare no breath to respond to their concern.
She quickly dropped to her knees, supporting her swaying body that way as she instinctively began analyzing that powerful, alien mana.
Even if personal factors normally prevented her from turning an opponent's own methods against them like a mage with copying eyes, analyzing its origins and countermeasures had already become instinctive for her.
