Deplete all your ember PP's, visit the nurse, get ember PPs back through the scene with phoenix again, continue to train against the robots till the MC says they feel like they can beat Phoenix (maybe train a level or two higher for an easier fight), find her in the hallway on a weekday, interact with her again and ask for another fight/training session and defeat her. I think having the mach punch ability and being a higher level also helpsView attachment 1151983
