Yume Nijino's Poolside Pose: The image features Yume Nijino, a character from Aikatsu Stars, dressed in a blue sailor-style swimsuit with red accents and a large bow on her head. She is sitting on the edge of a pool or water feature, with her legs dangling in the water. Her right arm rests on her bent knee, while her left hand holds onto the rope netting behind her. The background shows a sandy-colored floor with a metal fence visible behind Yume. The overall atmosphere suggests a fun and playful setting, possibly during a photoshoot or event related to Aikatsu Stars.
