The name is most popular in Arizona, Wisconsin, and New York, reflecting its appeal in diverse regions. As a modern coinage, Aizen lacks traditional etymological roots, but its association with a powerful and complex fictional character gives it a distinctive, edgy quality that appeals to parents seeking a unique name.
