/jp/ - Otaku Culture

I know, this is more /v/ related than /jp/ related, so don't tell me to go to /v/ because I did but, I don't feel like posting in a sea of posts. Anyway, this game is /jp/ related somehow because it comes from japan, and japanese vidya games are part of the otaku culture.

Has anyone tried this game? It seems to be very long, and there's not a lot of information on the internet, I has been searching for some walktroughs but everyone is still incomplete. There's also a place in the game called "Never Ever" or something like that (my game is not the english version), and requires a black cell to access it. What's that place and how/when can you access it?
