Box Weapons (匣(ボックス) 兵器, Bokkusu Heiki) are small cube-shaped boxes that store powerful weaponry inside. Though they are called Box Weapons, few actually come in the form of conventional armaments and the most are designed after animals. The greatest assets of these Box Animals, as they are called, are the special abilities born out of the unique traits of the Dying Will Flames that serve as their power source.
