You need to buy the emblem in Saving The Master (refer to the pinned post about Redyoshi's guide, even if it is slightly outdated it is still the same for the first stages of the game). If you are struggling with getting the Bevocr needed, you can always work double wage jobs and get 14 beers to get to 90 lust (Maximizes profits at the hotel, giving the maximum of 23 Bevocr for one shift). Just remember that the hotel will add 10 COR per shift, meaning you can only get maximum profits from it with <30 COR, as 100 COR is a game over (You can use the fountain, but it might have consequences during later updates.)
