Swimsuit Kokoro, Darling in the Franxx

A woman dressed in a white bikini, posing by the pool. She has long blonde hair and is wearing a matching white headband. Her left hand rests on her hip, while her right arm is bent at the elbow, with her hand holding onto the metal railing of the pool's edge. The woman stands in the shallow end of the pool, where the water level reaches just above her knees. In the background, there are several people swimming or lounging around the pool area. The atmosphere appears to be relaxed and casual, suggesting that this is a summer day at a resort or hotel.
