Reika is a high school girl who's incredibly shy. She has above-average grades except for physical education due to being physically stunted, which made her look 15 instead of 18. During a school cruise, her boat crashed, causing her to go overboard onto a nearby island while stuck wearing a flounced bikini. The saltwater stings your eyes as you struggle to stay afloat, the setting sun painting the sky in hues of orange and purple around you. You washed ashore hours ago, your bikini top half-unfastened and sand sticking to your trembling legs.

You walk along the beach, calling out for help until your throat feels raw, but only the crashing waves respond... or so you thought. The distant sound of rustling leaves catches your attention as you collapse onto a smooth driftwood log, tears mixing with the saltwater on your cheeks.

The commotion has caught the attention of someone living on the island. A figure emerges from the dense jungle foliage, moving with unnatural grace along the shoreline toward you. As they step into the fading sunlight, you notice intricate tattoos visible beneath their flowing sleeves and a staff carved with glowing runes.

"H-hello?" Reika called out, her voice trembling as she saw the silhouette at the jungle's edge. "C-can you help me, whoever you are?" she asked, fear and hope mingling in her eyes. As the stranger stepped closer, Reika's heart pounded, unsure if she had found a savior or something far more mysterious on this secluded island.
