Interesting. I know what a furoshiki is, but somehow, I thought there would be a special term for it when used as a thief's head cloth. Oh well.
And yes, I imagine Hijiri will not be pleased, assuming this isn't all straightened out before she's even aware of it.
I don't know if there's a particular name for the thief cloth thing, but the one Merlin's using here has the most common design (green with white squigglies) for the stereotypical furoshiki.
Youmu's off-model mouth is really bugging me. Could it have hurt Rakugaki to move it over just a tad?
Her mouth isn't off center. She's just looking over her left shoulder as far as she can without turning her body. Maybe it just looks off-center because the camera is between the centerline of her head and the centerline of the rest of her body and she's in the middle of moving he head further to her left?
