character: shun_(small)_(blue_archive), kokona_(blue_archive). A full body shot from a slightly high angle depicts shun_(small)_(blue_archive) and kokona_(blue_archive) relaxing on a sun-drenched tropical beach. Both characters are wearing cute, colorful swimsuits appropriate for the seaside. They are sitting closely together on the pale, sparkling sand, focused on building a detailed sandcastle; kokona_(blue_archive) is carefully patting the walls of the castle with her small hands, while shun_(small)_(blue_archive) uses a small plastic shovel to pile more sand around the base. kokona_(blue_archive) has long, streaked hair and animal ears, while shun_(small)_(blue_archive) has black twintails and fluffy tiger ears. The background features a vast turquoise ocean with gentle white waves crashing against the shore under a clear, bright blue sky. The lighting is vivid and warm, creating a cheerful, summer atmosphere with soft sand textures and shimmering water reflections.
