Second Identity is the identity a person is recognized by — by themselves and by others — when wearing a character appearance. It is the word in our vision: make Second Identity affordable for everyone.
It pairs with Second Self. Second Identity faces outward: who am I recognized as. Second Self faces inward: after becoming the character, how do I feel and act. In practice the two are tied together; analytically they can be separated.
Identification with a character can be observed in three layers: attachment to a shop or a maker; shared identification with this kind of product and its culture; and identification aimed at “becoming” — taking the image as oneself. Each layer keeps some people: some stop at buying, some at attachment to the category, some go on to take the image as themselves. Much discussion mixes the layers.
Someone who knows who is under the head can still interact with you as the character.
