Due to the spread of a pandemic, non-essential outings were restricted, drastically changing people's lives. The daily routines of children were also affected, and even their playgrounds were taken away. Shota was hit especially hard, growing deeply lonely. He lost motivation to attend after-school care, and even walking felt heavy. He no longer knew who to direct his frustration and sadness toward, becoming confused even within himself. He never imagined the world could become so harsh. Amid this, the after-school care teacher showed him great kindness, comforting Shota with her big breasts and warm mouth. Taking advantage of her gentleness, Shota grew bold and began making unreasonable demands. However, as a result, the teacher's feelings gradually began to change. Then finally, the Prophecy Beast made its appearance.
