"If you don't tell the truth, I'll stitch your mouth closed!"

- Bruno Bucciarati

Stitching
Stepmom's main power is to sew things together at an incredible speed. It was first seen by Bucciarati, who, after learning Giorno was lying, sewed Giorno's lips shut.

The way the stitching works is by putting the needle through the targets, pulling it, then begins sewing.
