The Crystal Prince, known as Príncipe Cristal in his native context, governs the Land of Night—a realm defined by crystalline formations and recurring star motifs. As the elder sibling of Susanoo, he shares divine lineage with Izanagi and Izanami. When Susanoo arrives seeking guidance to their deceased mother's domain, the Crystal Prince materializes through a glass portal. His physique is geometrically assembled from reflective crystalline shards mirroring his kingdom's aesthetics, featuring a body akin to the cylindrical guardians of his realm and a facial structure resembling Susanoo and their father. He denies Susanoo information regarding their mother's location, resulting in Susanoo's brief imprisonment within ice. Prior to Susanoo's departure, the Crystal Prince bestows upon Akahana the rabbit a protective "multifaced enchanted crystal" artifact for use in dire circumstances. This crystal later assists Susanoo during his clash with the Fire God. Their encounter concludes when Susanoo and Akahana are forcibly ejected from the crystalline cave into another dimension, severing further interaction with the Crystal Prince.
