As soon as you step foot into Stop 4 of Group Date Cafe, return to the Nurse's Office to receive this request, where you'll have to fight against Elizabeth. The fight takes place in the 3x3 empty room near the stairs going up to Stop 2. Depending on your team and your level, the fight shouldn't be too bad, but Elizabeth certainly isn't going to make it easy. She doesn't have any weaknesses, plus she has stronger than normal resistances for status ailments and binds, as well as nulling light/darkness. However, she can still be poisoned, which is going to be helpful in bringing her 4,000 HP down. That makes using Incubus with Impure Reach a viable strategy still
For attacks, Elizabeth doesn't have too many that will put you in serious danger right away, as all her damaging attacks are physical. In fact, she operates under stages in the battle, with her saying something and then putting more skills into her repertoire. She'll start out with Tempest Slash, which will hit a single character three times for light Cut damage, then later moves include Mighty Swing and Assault Shot. Other skills include Tarukaja, which raises her attack power for three turns, and can be very dangerous so you will either want to counter with Dekaja or Tarunda.
The most annoying moves she has are Binding Cry, which has a medium chance to paralyze your party, so either have some Patra Gems ready or have Me Patra/Null Paralysis on your Sub-Personas. The other move is Hamaon, which doesn't really seem to appear until late in the battle and it only hits one character at a time, so you don't have to worry about having your entire party wiped out. Thus, it's important to have someone with Recarm or have some Revival Beads in your inventory (which you should always have anyways).
As already mentioned, she doesn't have any resistances or weaknesses to elements or physical attacks, so feel free to let loose with anything. It might be wiser to use physical attacks, as you have a chance to get criticals, which will give you the Boosted state. Also, Incubus is one of the stronger Sub-Personas to have at this point in the game, due to the overpowered nature of Impure Reach making it so status ailments will almost always stick on the enemy. Combine this with Toxic Slice, which has a chance to poison enemies, and you will undoubtedly make it land more than once in the battle, helping to wittle down her HP.
