Hatsune Miku: Project Diva F

This title is awarded to you for purchasing every gift item in the store. Most are available at the start of the game for purchase. However, you also need to purchase each character's birthday cake, which requires you to raise their affinity to max (level 6) or visit them on their respective birthday (though I recommend maxing out their affinity as you'll get six additional trophies for doing so). You also need to purchase the Player's birthday cake, which is unlocked by giving each of the characters their own birthday cake. These cakes cost 30K Diva Points (aside from yours, which costs 50K).

Keep in mind you don't have to give out all the gifts for this trophy, just purchase them. However, many of them are needed for the "Memory Album" trophy. You'll also unlock the following trophies along the way (provided you raise their affinity rather than visit them on their birthday):
