Do you guys know that you can actually find Bogthos standing around at random places in the original castle? If you find him, he tells you all about the lore, the background and the past. The same with the the repeatable events between the girls (including Ayumi), except these events bring more exposure to their personalities/interactions rather than lore.
I'd have to say it's confusing why these details are hidden so far back in the castle where the player most certainly won't be returning often to after the initial stages of the game. It's no wonder why people think the girls have no personalities after corruption, because the only parts where they show their personalities/specialties the most is when they aren't with you. Or at least when they aren't presenting themselves in the usual contexts (e.g. Assisting in corruption, fucking, worshipping you)
For example, Ayumi would thank Rina for the martial training she provides, Misaki ensuring that Ayumi is adjusting well to her new abode. It really is a shame that these interactions are sidelined from the main course (SEX) in this game. I feel that there is a lot of missed potential here.
Another point of note is that it is incredibly frustrating to trigger random events sometimes, I could be running laps in and out of Hikari's chamber only to see Yukako ask her whether she will worship Master the tenth time. Once you've triggered it, you better not be holding down Z/Enter/Spacebar for more than a second, otherwise you'll miss those dialogue and be forced to run laps in and out of the room again. Having no replays for random events suck ass.
Alright, feedback over, time to run a thousand laps on the castle's stairs and play hide and seek with Bogthos the Lorekeeper
