Devil's Tree

As you progress through Devil's Tree, you can improve a card's attributes, raise its maximum level, earn items, etc. In order to progress, you will need specific upgrade items. These items can be earned by winning dance battles and completing missions.

Only by unlocking all of the spaces in a card's normal and secret Devil's Tree can you unlock a card's full potential and reach 100% progress for a card.

SSR, UR, and UR+ cards have slots that unlock outfits, backgrounds, character voice lines and chatrooms. From SR and above, all cards have icons that can be unlocked. Every rarity type has items that unlock a variety of things, like Grimm or surprise guest gifts.
