Hyper-Density Seals

Hyper-Density Seals (超質量印) are weapons utilized by Sir Nighteye.

Description
Sir Nighteye possessed a number of small, stamp-shaped items that each weighed five kilograms.

By throwing the seals at extreme speed, Sir Nighteye could attack from long range and supplement for his lack of a physical Quirk. A seal tossed by Sir Nighteye was powerful enough to destroy one of Twice's doubles in a single hit.
