I was watching this video and the youtuber seems to have triggered this scene, but Susie gives Kris an "Ancient Chocolate" instead of an "Ancient Sweet". I don't see mention of this anywhere, so I am posting this here to bring attention to this so that people investigate.
I am writing this just after going through that scene in the video so I don't know if the item description is seen later. I guess the youtuber followed this save file from Chapter 3, and at the end of her previous Chapter 3 video her current items can be seen in the Knight fight, but I don't really know if she continued it from earlier or just started it from there. Thanks to UI elements we see that she is playing in Play Station but I don't know if 4 or 5. I assume 4 as at the start of her Chapter 3 video we see a loading screen.
Anyways, that item could be called like that for several reasons. Maybe if you have an specific item combination through your save files it is a chocolate instead of a sweet. Maybe if you start it from Chapter 3 it is different than from Chapter 4, assuming that everyone who encountered this did so by starting the file from 4. Or maybe the item is named differently between versions, maybe we only know of the sweet because people have only datamined the PC version regarding items and haven't checked the other ones. Unless, of course, the item name was changed in an update. Maybe in the initial PC release it was also a chocolate but one of the hot fixes changed the name and it is still a chocolate in the console versions because they are not updated yet.
So checking other combinations of the item story in the save file, datamining further, or checking the other versions of the game might end up in discovering new things about this item. My most probable hypothesis is that the thing has different names in each version of the game, thus probably in the Switch version it is also called chocolate or even something else. But if so, both the Switch 1 and 2, and the PS4 and 5 should be checked in case it is different between those too. Or even Windows and Mac? It would be worthy check the initial PC releases in case it was indeed renamed in an update. idk, I can't really check any of that stuff so I ask people here who can.
At the very least what we know here is that there is a variation of this item that is called chocolate instead of sweet, which is not documented anywhere, so there is something that we are missing.
