What is password for this file?

I want to Know password for this file so much. This File!! Saiaku no yoru [twinge].rar
I try to unlock it but I can't.
Anyone Please tell me for password in this topic,or PM.

Thank you for all supporting for me.

I'm afraid is not possible to "guess" or discover a password when a person upload a pass protected file to any server. Any the uploader knows the password. I dunno how did you find this file (at Aarin? in a community? Googling it?) but my best suggestion is that you contact the person who upload the file and ask for the password. If this file is linked in some thread at Aarin, usually the password is posted in the thread.
