Demon Girl's Secret Wait by the Rainy Window

In a classroom where rain pounds against the window, a horned girl crouches, gazing at the outside world. She's a demon disguised in the human realm, cherishing these after-school moments. Her wet uniform clings to her skin, and the raindrops in her blue eyes evoke memories of home. Soon, a meeting with a friend will spark her adventure. Her heart sways quietly to the melody of the rain.
