The innocence requirement is gone in 1.8.x you only need to do nanami quest and talk to her in front of the town hall
Fix worked another issiue i found is that after day 21 when getting the true ending MC says she cant wokr (as a hooker) because its th last day to pay even tho the mayor is dead.
And the 7 deadly sins after killing them there is no reward dude says to come back another day but at the same time he says there is no active demons.
Last one is at day 25 she says she cant sleep yet but i cant do enythink more its late night no work no sleep nothing is something supposed to happen like the attaack on the city?
Did you finish the quest in day 25? you must talk in the lab then guy in the back of uwus (and thanks for reminding, I need to track that one asap)
Are you sure about the seven deathly sins quest? didn't you get maid oufit? I'm asking because I personally tested it and everything seemed okay by day 18 they all spawn and they are in: Town hall front, Burger shop, love hotel, game store (east zone), old mansion, inside the mall and around the bar. I think the dialog could be bugged tho.
Also, it gives you the chance to get a strong weapon based on preferences.
You can defeat easily the 7 demons with gimmicks.
Greed for example you toss money and he will lose half hp
every sin has something like this.
I will check the hooker/npcs I might have an idea whats happening
