I for the life of me cannot get the 9th question mark in Evergrind City, in order to get the star. I'm at 6/6 items, 4/4 exclamation marks, and 8/9 question marks. I've also done all 8 maps. I S-ranked the two Colosseum fights and collected the Egg shell, Pope hat and Crown. I opened all the chests in the Colosseum room as well. I bought the house, completed the alchemist quests to have 3 potion slots. Does anyone know what else I could be missing? Thank you!
