[Akimitsu-dono sits unmoving as always - and yes, the paper eye is stuck firmly on a skull covered in bandages, if she desires to lift it up. Any examination of that should reveal that the bandages are wound tightly, and the skull feels intact and solid underneath.]

I also did wonder that as well, and I did go to quickly check on him...but it seems his skull is still here. Which means someone else may have something of the like, or someone somehow retrieved a skull from someplace.
