If you have advanced Ayumi to corruption level 1, then you have done everything you can on the Yuma front(that quest is not complete yet and won't change after you have done that step). If you haven't you can find Ayumi in the zerethin wall dungeon.
I honsetly can't remember. Haven't played since 2.5 but it seems like I can't really activate any new content - apart from a sidequest about orc troubles. Am I missing something obvious?
If you have captured Hypatia, you can talk to Yukako and Ayumi(as long as you are running 2.7) to start some quests, and talk to Misaki to do the first corruption levels for Erina(2.6) and Hikari(2.7). They can all be found in the castle meeting room.
I did not have that problem. Have you set up trade between the succubus village and the desert town yet?
If you can't get the succubus village to work, the merchant on the ground floor of the dukes building in Vlester is also an option for that quest.
I believe that is it for this update. If you have done that quest and the Hikari corruption stuff then you are done for this update provided you were already caught up on side quests.
Yeah that seems to be the case at least on a minor level. She was most certainly the one that came down making it easier to dispel the illusion on Zerethin's tomb and is probably the cause of Hazuki's dream. I also wouldn't be terribly shocked if it is revealed that she played some role in an arrogant dick head like Romanos being chosen as champion. My personal head canon is that there was actually an argument in favor of making the MC or someone else more competent champion, but she influenced things in Romanos's favor due to subconscious orders to keep the divines from gaining too much strength.
