Kachimachi Kosuzu, with long brown hair in braids and blunt bangs, stands on the left, her hands clasped together in front of her. In the center, Murano Sayaka, featuring long blue hair in low twintails with ribbons and a mole on her neck, leans in with a cheerful grin, resting her hand on Kosuzu's shoulder. Yugiri Tsuzuri, with short multicolored red and white hair and star ornaments, stands on the right, waving her hand with a gentle smile. All three girls are wearing short-sleeved summer school uniforms consisting of white shirts with sailor collars and matching skirts. The background is a detailed classroom with wooden desks, chairs, and a chalkboard, with soft sunlight streaming through large windows. The visual style is a high-quality anime illustration with a bright, warm color palette and a joyful, nostalgic atmosphere.
