character: narukami_arashi,suou_tsukasa,sena_izumi_(ensemble_stars!), sakuma_ritsu. The image depicts a dynamic underwater scene featuring the five members of the unit Knights (Ensemble Stars!) transformed into mermen with shimmering, translucent fish tails. They are swimming amidst deep blue water filled with light rays and bubbles. In the foreground, tsukinaga_leo is seen from the side, looking back towards the viewer with an energetic expression, his orange hair flowing in the water. Behind him, suou_tsukasa swims gracefully, his red hair and purple eyes prominent, with a calm demeanor. narukami_arashi is positioned centrally, blonde hair spreading out like a halo, wearing a pearl necklace, with a gentle smile. sakuma_ritsu and sena_izumi_(ensemble_stars!) swim slightly further back, ritsu with his black hair and serious look, and izumi with his grey hair and serene expression. All characters are shirtless, their upper bodies wet and glistening. At the bottom of the image, the text "KNIGHTS" appears in bold gold letters, with the subtitle "sirens" written in a smaller, elegant script below it. The artwork is a high-quality anime illustration with vibrant colors and detailed water effects.
