I don't think so. In the two playthroughs I have, the only scenes I've seen with Hanako is the first one in China, one at the pool and one with her, Matilda and another friend in the gym.
Actually, I don't think I've unlocked Caroline, I can be mistaken, but I searched the glossary, and haven't her, although, some of the girls go by nickname there.
I see two locked scenes in Hanako, one of them seems to be with Isabella, though I did not get. I don't know if this is a bug though, I got more scenes with Hanako whe I choose to avoid the orgy, the in that playthrough I ditched Isabella. The playthrough I didn't ditch her, I went to the orgy, and there were no more Hanako scenes, just the first one actually.
Btw, thank you for the responses! I loved the game, will help through Patreon some time this week. It seems impossible to get all scenes in one laythrough though, since some choices are decisive, and thats ok, but maybe it would be a good idea to have a walkthough, even if subscribe only.
