Compress (コンプレス Konpuresu?) is a Quirk possessed by Atsuhiro Sako.


Compress allows Atsuhiro to shrink anything in a spherical area into a small marble without actually damaging it.

To activate his Quirk, Atsuhiro first needs to touch the target with his hand. This will result in the target getting shrunk down to a minuscule marble-like object. Compress will affect anything that is found within a specific range of space around the intended target, including, for example, fire or pieces of the ground (the exception being Atsuhiro's own arm). The weight of the compressed objects is reduced considerably, making it possible to hide or carry them around. Atsuhiro can release a single marble by wishing it, or all of them at the same time by snapping his fingers.

When used on a person, Compress effectively entraps them, terminating the fight in an instant and letting Atsuhiro abduct them easily. This is particularly useful against opponents who are resistent to certain forms of attack, such as Snatch. If Atsuhiro focuses on an area smaller than the target's whole body, he is able to compress only said area while leaving the rest of the target's physique unaffected, mutilating them in the process.


It appears this Quirk can be used in absolute stealth, without noise and before the victim can attract the attention of nearby allies.

This can come in handy to lay traps, which he demonstrated by throwing a marble under a police car and releasing his Quirk, causing the rock he had "compressed" to instantly recover its original size and launch the car upwards.
