Krafton is an alliance brand that provides an environment in which a variety of game developers can grow in synergy. The visual hierarchy between the group brand and each union brand was not clear. To solve this problem, we have re-established the brand architecture by creating a design system that expresses the uniqueness of each brand and the consistency of the group brand simultaneously, so customers can intuitively recognize and experience the brands individually and collectively. We have established a brand structure in visual language.
