which forms are giving you trouble?
okay so you're looking for "barmaid reese" and "barmaid marazet", but both of these forms also combo with "maid" if you hit maid first. you will have to ally with Richter for these forms regardless, and once you do, you should be able to tf them through the transformation menu during mingle phase 4 after the bar scene takes place. for exact details on how to do this, check "Maid alliance route" within the "beginning the barmaid quest" section of the walkthrough.
