The Heki Heki no Mi (Heki being the Japanese word for pierce) is a Devil Fruit that allows the user to pierce through virtually anything.
Strengths and WeaknessEdit
The most prominent strength of the fruit is that the user can pierce through virtually anything, just with the tap of a finger. If honed well enough, the user can actually pierce the very air itself by only pointing at it repeatedly.
Thus far, only the standard Devil Fruit weaknesses seems to plague it.
