Irrégulier

  Irrégulier (イレギュリエ) is one of Larxene's weapons in Kingdom Hearts 358/2 Days.

Design
True to its name, an Irrégulier knife has an oblong shape, somewhat similar to Xemnas's Fury model of Ethereal Blade. It has an "S" shape with a small, red handle. The rest of the blade is black with gold edges.
