Space

 (空間, スペース, Kūkan) is a Curse that involves manipulation of space.

Description
Space allows the user to manipulate the space between or from inside an object. Space can also be used to push a target, by expanding the space in front of it. The user may also increase the strength of physical attacks by quickly expanding the space around the user's limbs, before the attack could hit. However, improper control of the Curse can lead to death (i.e., crushing by decreasing space around the target).
