Can someone enlighten me? Beating the game unlocks the full gallery, however there are several entries that are sort of "missing", or just can't interact with them (like number 11-14 named 'dialogue 1-4' or number 16-18 named 'futanari 2-4').
Also the 'missing' entries can be separated into two categories, one where there is nothing next to the number and one where it's kind of crossed out (like enemy animation number 9)
I'm fairly sure that nothing is missing, but this trivial 'mystery' is driving me crazy, so if someone can shed some light on this, it would be greatly appreciated.
Some bonus info, I've done everything the game has to offer (I hope) except the RD dungeon challenge where you have to beat it at the initial level (actually no idea how to do that since you level up automatically once enough xp is gathered)
