- customize how the main character looks
- exchange Digital Devil Service cards over StreetPass
- These show your character’s level, a demon you select, and a canned message
- exchanging may lead to a special fusion
- Example: Jack Frost returned with a black card that triggered an indiscriminate fusion that changed him into Shemhazai
- use the same spells and abilities as demons
- this is learned through the whisper system where demons can pass down abilities
- when Murmur whispers, players can choose a skill like Mudoon or Maziodyne
