[MMD] An Interesting Find

So I found these models (not the stage) just the day before they're supposed to be expiring because they're all limited download until 10/1/14. I don't know if that's supposed to mean until AFTER 10/1/14 ends but they are still up right now. If you can, try and figure out the passwords before they're time is up. I'M ABSOLUTELY NOT HELPING ANYONE, not even giving the teeniest hint so you're gonna have to figure it out yourself. Why? Because I took quite a bit of time to figure it out so I don't want people having an easy time getting password protected MMD models. Besides, I don't think anyone wants them anyway... I don't even know who they are... I'm guessing that the left and right ones are Flandre and Remilia Scarlet though but there are a lot of those so who'd want these anyway... Here is the link: bowlroll.net/file/52574 .

EDIT: Well, the downloads are now down because the time limit ended so too bad for those who asked other people to help them out and then they couldn't figure it out themselves because they're too lazy to find the answers themselves.
