Hisen's Fatal Stroke currently has a visual bug that results in any enemies you've hit with it duplicating their sprites whenever it activates!  These sprites will typically place themselves on the location of the Hisen's user, as well as face in the same direction they were facing before.

All one really needs to do to replicate this is to use Hidden Cut with Fatal Stroke toggled on.

This should be corrected in 2.88.
