Dragnir

ドラグニル

His full name is "Draconir, Knuckle Dragon". Unlike other Digital Friends, he can speak, a fact he is unaware of the reason for because his memory data was separated from him.
Light Tenryu receives his card in the deck that Wolfram Zerga gives him. When Light installs the deck on his smartphone, Draconir appears, surprising Subaru and Itsuki by being able to talk.
Draconir supports Light in his battles, talking with him whenever he draws his card.
After learning that Draconir's memory is stored in various data devices held by the Seven Shadows, Draconir and Light set out to retrieve them to uncover the secret behind Draconir's origin.
