I think I've done all I can of the story I have 95/95 events And 95/99 secret events most of the relationship quests are done as well except selena and elith the bartender can offer nothing and I don't think the fortune teller can ethier HELP!!
Go to the fortune teller... During the day... And ask her... About improving relations... with all the characters... on the list...
But seriously, you have six options (this may depend on the version number of the game) with whom you can try to talk: the fortuneteller, the bartender, the team of Captain Ceres, the inhabitants of the Dark World, Kimiko, Edgar. Because there shouldn't be any hidden characters.
It’s difficult to say more precisely - we don’t have a crystal ball.
