He needs to kill or get rid of these ****ers. Hopefully as soon as possible, get evidence on who they all are, then go do some dark shit to them and post his findings to the police, reporters and the internet. Obviously protect the victims identities while doing that. That way they get put away for good and exposed, no leaving this and then having one of his girls get kidnapped and the whole cliché rescue arc of the story. End them now hard and fast.
Sigh this can't keep going on, it is obvius that this world keep spaming rape bastards everywhere to corrupt/rape mc's girls, he is fine so far But he is still An underdog that relys on his hacking skills and his knowledge of the future, catching them offguard. The fact he can fight now is good so far, but eventually somebody Will catch him offguard and rape his girls He need to "start" thinking in create his own power and influence to deal with the real dangerous predators out there, i'm not saying he got a multinacional company or yakuza Underworld power right away, but he need to start thinking about it He can't be everywhere, and this hack and treath thing has a limit
So if I was in his place, once I caught Akira I would threaten him to call his friends waiting at the hotel. That something happened and a change of location is needed. Where the I could easily kill them all then dump the bodies. It's just better to kill scum before they try to hurt more people. This MC needs to nut up or shut up and let his girls get raped if he doesn't grow a stronger personality of killing those that need to be killed.
