Weapons (武器, Buki) are a type of equipment in Kingdom Hearts Birth by Sleep. Terra, Ventus, and Aqua can each equip one Keyblade, which increases their stats; weapons available to multiple characters have different designs for each member of the trio. As world-exclusive party members are limited to specific encounters, they do not have viewable inventories with weapons.
