Thank you for explaining. I thought he was scared of an immediate threat like getting drugged again.
I'm still a bit confused, if you could help me understand better. How is she planning to isolate him from his group? Based on what you said, I'm understanding that she is having his group be too enmeshed with her group (and therefore her) that they can't separate from her at all and have more reasons to be even more entangled. This makes it so that in the future, they disregard his concerns further. Am I on the right track?
I feel like there has to be away to expose her, but she seems to have video and audio devices keeping track of him at all times. That would alert her of anything he tries, which then with early knowledge, she can thwart any attempt he makes. So I have no idea what he can do. I don't know how stalking is handled in Japan, but it's typically not taken seriously until it's too late in the United States. I can imagine a male being stalked by a female would be ignored harder by the police here. And then an accusation of a celebrity stalking someone fairly unknown would make the stalking claim be dismissed as nothing even more so.
She already isolated him by making clear keeping her eager to advance the group's career is in everyone's interest. That power dynamic is made clear when Nagisa tried to tell what was happening to his manager. I don't remember if he had time to get specific but the manager did get the gist and she doesn't care, she straight up told him to 'put up with it'.
And unfortunately, this is something still very common in the entertainment industry (and many others, really anything with money floating around and power). Those at the top can and do treat the attractive newcomers as they're personal escorts, and a lot of people supposed to protect them instead either close their eyes to the danger or even worse, facilitate it.
It usually happens to women but men aren't safe either. For example, I heard an interview recently from Alan Richardson, the actor playing Reacher, huge buff dude two meters tall. When he was a model, he was once sent for what he thought was a job or business meeting, but it was only someone influential wanting to fuck him. He had to put his foot down with his manager to not pull that shit with him again and/or do his best so that it doesn't happen again. That's a vicious environnment because not everyone is confident enough to do that and risk blowing up their career when it's just beginning.
With this story, the fact that this is usually a concern for women makes some men like Nagisa even more vulnerable to it because they didn't expect it, and there's even more social stigma for male assault so it's even harder for it to be treated seriously.
Japan is already terrible dealing with the widespread and known female assault, so imagine how little will be done even if he reports it. Everyone will be more likely to pressure him to forget about it and bare with it, to keep up face and not cause waves.
Having said all that, the online communities in Japan especially do love to uphold moral integrity and justice, and would also jump at the chance to take down someone evil and criminal. If Nagisa manages to break Kura's angelic persona and make her show her obssesive and scary side live, it could save him by having her fans turn her for making their new fave uncomfortable.
Predators are only truly safe in the dark, in private. Once they're exposed, it would be social suicide to support them. The fact that people are cowardly sheep like that is the only effective way to deal with them, why it's important to make serious noise and have real consequences when caught or else it emboldens the abusers and deteres anyone to seek help and help the victims.
