Miina-san (pseudonym, 20 years old) became the center of a controversial incident that occurred on a train, where an inappropriate act took place in broad daylight. Despite the presence of other passengers, a man sexually assaulted the woman, and instead of intervening, bystanders reportedly used their smartphones to record the scene. There are also reports that the man applied some substance to the woman's genital area. The man's bold behavior may have led onlookers to believe it was an AV filming. Further details of the incident will be revealed in due course.
