"How do you get the last CG in the Gallery?"

Friends, I have gathered here to answer your question in times of need. Well, not really. That exact information is exclusive to patrons, specifically Blooming patrons. You specifically need to go to this post and download the second file attached to it (the one that says "CG Gallery Guide") if you are a Blooming patron. That document will give specific directions on how to get every CG currently in the game and is updated with every CG that gets added to the game. Keep in mind, however, that it draws information from the regular guides, which you can view in this collection here.

Now if you're not a patron and you're lost at what to do, what I can do is give you a few hints. First, I'll tell you how many CGs each route has:

Brendan's Route - 9 CGs (This includes one CG that you can technically get without being on his route)

Kamil's Route - 11 CGs 

Connor's Route - 4 CGs 

Common Route - 2 CGs 

Side Stories (Tales) - 2 CGs

Another thing is that some CGs require doing different things in previous days. For example, an option to view a scene that has this specific CG might be locked behind doing certain things in Days 3 and 5. But it also could just be options you've made earlier in the day that affect what CGs you get. Cut-ins, any art that only takes up a fraction of the screen, don't count as CGs by the gallery and therefore don't get any entries, so don't worry about collecting all of those. Finally, I'll mention is that Kamil's route currently has the hardest CG to obtain in the game so far.

So yeah, every time anyone asks a question relating to the CG Gallery, I'll just link them to this post.

Have a good day and see you later.
