"Right," you say, transforming in a burst of light and smiling at her. You drop to the floor, sitting cross-legged as you summon a small sphere of Grief to your hands. It clinks against that Grief ring, the one you never did dismiss. Of course, your finger's still happily uncorroded by Grief. "I'll be just a bit, alright?"
You draw in a breath and focus. Locating Sasa Yuuki... a compass. A compass to locate Sasa Yuuki.
You push with your mind, with an ability that rises to the forefront of your mind like a limb you don't have. You force your will on the Grief, trying to mould it into a shape, and-
-a blinding migraine sledgehammers you between the eyes, an icepick driven into the crevices of your mind.
Your breath hisses out of you in a pained gasp, and you drop the Grief, squeezing your eyes shut.
Homura's at your side in an instant, hovering almost anxiously as she touches a hand to your shoulder.
"I-" you draw in a shuddering breath. "I- I'm OK. That was just- yeah. You know. When I fail to make something. I get a massive headache?"
"Mmm," Homura says, brow furrowing as she inspects you.
You sigh. "That didn't work, which means..." Lots of things, really. For example, that you really can't seen to extend your sensing range beyond the existing two hundred odd range. Or at least, not with Grief. But the more relevant thing is that it means... "Manual searching," you sigh.
