Anime illustration of two sad girls in a classroom at sunset, one crying on a windowsill, the other a translucent ghost.

> A melancholic and emotional scene in a quiet classroom during late afternoon. A teenage girl with shoulder-length black hair, wearing casual clothes, is sitting alone on a windowsill, looking outside with sadness in her eyes. Next to her stands a ghostly figure of a girl (Nika) — she has short black hair, a slightly tomboyish outfit, and a glowing, semi-transparent look. Nika looks at the girl with deep sorrow and guilt in her face, as if she regrets leaving. The classroom is dimly lit by soft orange sunset light. There are old wooden desks in the background, and the atmosphere is full of silence and pain. The two are close but emotionally distant. The ghost stands just beside her, but they don't touch.
