As a fair warning, I might have not gotten all the stuff and my character is grossly underleveled. However, I beat the game and there's a gallery room. So, here's a save, I guess.
Edit: I suppose I should write a few things about the gallery. It seems to unlock everything, even CGs you haven't seen yet. So don't worry about collecting every CG if you're playing the game by yourself. There's two parts of the gallery. The southern part of the gallery is all the CGs with the heroine, whereas the northern part of the gallery is all the CGs with secondary characters. No clue what the buttons in the southern part. The Red Icons are GoR CG, blue icons seem to be a few selected attack animations, some including punching and some including H content. Nothing gory.
As a final note, there's a part where you're on a train and might have difficulty navigating. I didn't know what the hell to do, but I managed to get to that area's boss. I killed all the mobs (which I don't think is necessary, but maybe) and then found a room with a treasure chest in it. I just went straight left until I found the boss.
