Eino Chamberlain

A passenger in the first-class coach.
At first glance, he appears to be an ordinary mature man, but in reality, he is a trafficker for an underground organization that pimps out comfort women to brothels in the war zones.
When he tries to recruit comfort women by pretending to be a nurse in a fake "recruitment for military nurses," usually, a whore who knows the situation applies for the job, but very rarely, a girl with a clean body like Somian arrives. Of course, they may be mistaken. However, amateur girls with little experience fetch a high price as they are reserved for officers. There is no way they would turn her away.
Eino tricks these unfortunate girls and takes them to a place far from their hometowns so that they can never escape by themselves, and turns them into high-class prostitutes for trafficking.
However, since inexperienced girls are not suitable as prostitutes, he forcibly commits adultery with them on the way to the destination. If the girl resists violently, he forcefully trains her, uses aphrodisiacs, and forces her to face the harsh reality of her situation.
Aside from the individual circumstances of the girls, there are many soldiers in the war zones who, under the influence of the fake posters, mistakenly believe that the nurses are comfort women, and this has become a problem.
There are real nurses in the war zone, and the Red Cross has complained about the fraudulent "recruitment of military nurses," and organizations in various countries have begun to take action to expose them, but the activities of the patching organizations are too sophisticated to fully grasp their true nature. The organization has a stick with a long, slender sword inside.
