Can't work past visual obstructions

Even if Fujino knew where Shiki is hiding, as long as she couldn’t actually see her, Fujino’s spell would only hit what Shiki was hiding behind.

In that brief clash on the bridge, Shiki had already read Fujino’s spell, and withdrew to a place where she could have a fighting chance. It makes Fujino realize how disadvantaged she is in fighting. Even so, I am the stronger one, she thinks. If I can’t see her, then I’ll strip this place bare. Randomly, Fujino starts to destroy anything that might offer cover. Support pillars, stacks of iron poles, guardrails, wall partitions—with each twist and crack of concrete, Fujino’s pain throbs faster, and the tremors in the building grow stronger.

“Okay, now you’ve officially lost it,” resounds a voice in the shadows. Fujino turns toward it, the sound seeming to come from behind a pile of construction materials. She destroys it in a blink of an eye, only to see Shiki dart out of it to the side.
