The only wielders of this weapon are Lealg, his nobody,Gellax, and James, son of Gellax.
The Masked Luck's teeth look like streched out dice with the top having six black dots, the middle four and the bottom two. The teeth go across the blade to the other side to make six, four and two. The keyblade's handle guard is see-through except a few strands of white. The handle and blade both look like the handle guard. The keychain is a dice, except James's is a colorfully tinted glass cube.
The keyblade is first seen in Organization Final.
