Hyper-Density Seals 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.[1]
