Re: イントルーダー
Alright I have figured out a few things.
Box - To use the box properly you must hide between other boxes. So unfortunately MSG style hiding (pretty much in plain sight) does not work in this game.
Password lock - You get a series of randomly generated codes, and only one of the set is correct. So it's a game of trial and error. Yuck. After an incorrect attempt, you have to exit the area and try again later on. I am not sure how "late" is later on.
Seducing the guards - You can only use the seduction skill three times before the guards are sick of you unfortunately.
Pushing - you must be wearing the stealth suit in order to push objects around. There are staircases hidden underneath some of the objects (usually book shelves). If something is hidden underneath there will be a black shadow. Also, I found letters hidden behind two of the bookshelves in a certain room.
Money - You can use money to bribe the guard if you are captured trying to hack an electronic lock. You can also use money to buy tickets into the onsen or buy chips for gambling. Not sure what else money is good for.
Virgin ending - in the room behind the church is a chest labelled virgin something. To unlock it you need a code. It's probably a reward for completing the game as a virgin.
