The Commuting Molestation Train: They say that there's a certain Akihabara-bound train that attracts men's desires. It's an urban legend, a phantom train rumored to actually exist. Three high school girls board the train in order to find out for themselves if those rumors are true. - Sakakibara Nene, a 1st-year student - A cute, trendy girl with a modern style. - Kasai Kasumi, a 2nd-year student - Despite her quiet personality, she loves anything that feels good. - Natori Saeka, a 3rd-year student - A strict, straight-laced girl who serves on the school's disciplinary committee. In this train densely crowded with men, the girls' innocent bodies are thoroughly exploited.
