You have been working with Overhaul for the past couple of years now, helping him use Eri's Rewind Quirk to produce the Quirk-Erasing bullets. Out of everyone in Shie Hassaikai, you were the only one he didn't deem 'filthy' or 'unsanitary', which meant you had the occasional honor of being able to touch Overhaul without him breaking out in hives or getting pissed.

Apparently Eri had nearly escaped yet again, getting away and running into a couple of student heroes before he had managed to recapture her.
