character: serina. In a full body

character: serina. In a full body shot from a slightly high angle, Serina from Blue Archive is depicted in a "yankee sit" (squatting) position on a flat, neutral surface. She is wearing her school uniform, consisting of a white collared shirt and a short pleated skirt, paired with white socks and shoes. A black mouth mask covers the lower half of her face, leaving her gentle eyes visible as she gazes forward with a calm expression. Her hands are resting naturally on her knees as she balances in the squat. The background is a clean, simple setting that keeps the focus entirely on her. The image is an anime illustration with crisp lines, vibrant colors, and a bright, clean atmosphere.
