An attribute (属性 zokusei) is a characteristic located at the bottom right of every member card.
An attribute is text describing the card. For logicalists, it describes a primary personality trait of that character, while for foreigners, it describes their race, the type of being they are. Tranceunions have the attributes of both the logicalist and the foreigner that combine into that tranceunion.
Attributes have no direct effect on gameplay, although they may be referenced by abilities.
