Uehara Ai is a cute, obedient and charming schoolgirl with a passion for painting since childhood. She is a quiet person, so no matter what happens, she will solve it herself, find out, but she will definitely not tell anyone. The incident began one morning when she took the bus to school as usual, but this time it was different, the bus was full of men with very aggressive and lewd generals, only she was a girl. Fear began to pour in as an eager man began to approach her side and act pervertedly, invading her sensitive private area while everyone around her was indifferent even though they saw the whole thing happening. She was frightened when she suddenly remembered what he was doing that was very familiar to her, and when she calmed down, she realized that it had some similarities with one of the paintings she had painted. After the incident, she hurriedly went to find those paintings to correct them but could not find them. Accordingly, the painting she created depicts a scene of a female student being gang-raped by all the perverted men on the bus. With her curiosity and desire for exploration, she decided to venture into finding the answer to the mystery of whether she is the female student in that painting by daring to take that same bus ride the next day.
