Located deep beyond Warabe Station is "Botsuda Convenience Trading Co.," where a mysterious beauty appears. She emerges with enigmas—where she came from, why she's here—and pleads for help, asking you to take on a request so she can uncover her true identity. She mentions, "I love basking in the sun," but offers no further information. After accepting the request, her memories slowly begin to return, and one unexpected event follows another. With clues pointing to her I-cup bust and her fondness for sunbathing, her hidden past and concealed truths gradually come to light. The story takes an unforeseen turn.
