Epic Trio: Guardians of the Sky!

character: chisa_(wuthering_waves), iuno_(wuthering_waves), augusta_(wuthering_waves). A medium shot captures four young women standing together in a misty, ethereal landscape under a twilight sky with swirling clouds. Chisa_(wuthering_waves), a teenage girl with long black hair tied with a red ribbon, blunt bangs, and piercing red eyes, stands at the center wearing a black serafuku school uniform with white sailor collar, red neckerchief, long sleeves, black pleated skirt; her hands are clasped in front of her with a calm expression. To her left, iuno_(wuthering_waves), a lithe figure with very long blue twintails adorned with ornaments and blue eyes, poses gracefully in a flowing white dress with bare shoulders, armlets, thighlets, and bracelets, her right hand gesturing outward elegantly. To her right, augusta_(wuthering_waves), with very long red hair, hair between eyes, and red eyes, stands confidently in ornate white dress armor with earrings and jewelry, left hand resting on her hip. The background features jagged rocky formations, floating ethereal particles, and soft purple-blue fog. Dramatic rim lighting from a low light source casts long shadows, with a cool color palette and subtle depth of field blurring distant elements for a mysterious, otherworldly mood.
