As before, Elizabeth has detected another spatial void on the bottom floor of Group Date Cafe and there's also an unknown Shadow there. To prepare, you might want to make sure you try to cover any elemental weaknesses of your party by equipping the accessories that reduce that elemental damage. It takes normal damage to every element and physical type, but is also weak to wind. It is able to be poisoned, so that's definitely something you want to do to whittle down its HP.
For attacks, the Engage King has access to the all-party mid-tier elemental skills (ex. Maragion, Magarula, etc) and will usually precede this by using Mind Charge on the turn before. That means you should probably defend on the turn following Mind Charge to minimize the damage of its spells. Once its HP reaches below 50%, it will start getting two actions per turn and will also start using Silent Song, Muscledown and Spiderweb. They hit your entire party and can inflict Magic Bind, Strength Bind and Agility Bind, respectively.
Once you've defeated the boss, go to the spatial void behind it and you'll get the Pink Orb. Bring that back to Elizabeth to finish the request.
