Conceptual Weapons (概念武装, gainen busou?) are magical items that have often an accumulated history and cause more than physical interference as they execute a certain built-in "concept," a predetermined phenomenon.[1] There are a variety of concepts that Conceptual Weapons can enforce, including "the negation of immortality with the concept of a natural life", "severing and binding", and "absolute defense against thrown weapons." Some are made to directly crush the soul with a concept. Formless things such as manifestations of laws or delusions are unable to be affected by physical interference, but Conceptual Weapons are able to damage them because beings born from concepts can only be killed by concepts.[2]
