Companions

The Phantom Companions of Jumper (50cp): What is a Heist without a crew? Unlikely to succeed, of course. You are friends with, or are going to meet and befriend, some people with some talent, loyalty and the capability to awaken their Persona’s. You can import companions into this role if you want to. Each companion purchased or imported gains 800 cp to spend on perks or items, but they cannot purchase other companions.
Social Link 10 (50cp): Or maybe you already have your eye on someone who is already here? During your time here, you will find that you have plenty of opportunity to spend time with your chosen character, and if you successfully convince them to come with you, they will be able to follow you into later worlds. You can take anybody except the protagonist, who has his own option below.
NASTY CRIMEBOY (500cp): Otherwise known as Akira Kurusu or Joker, you seem to have befriended a rather interesting character indeed. This is the leader of the Phantom Thief of Hearts, The Wild Card, The Trickster Archetype. He has a strong sense of Justice, an Assertive Nature, is incredibly loyal, and is fairly Snarky, but outside of that he’s a bit of a blank slate. He has the Joker Perkline, The Phantom Thief of Hearts Perkline except for Life will Change, and "You are a slave. Want emancipation?”.
