不霊夢, Fire Ignis

Flame is a small digital humanoid being. When not in a solid form, his body is red prism-like data. Like Ai, a fellow Ignis, Flame has markings over his black body, which is tinted red, in red flame shaped markings and thicker lines than the lines on Ai's body. He has yellow eyes that are semi-oval, giving him a more mature appearance.

Flame is the fourth Ignis to be terminated.

When Windy reemerges from Flame's body, he attempts to drain he life out of the latter and destroy Soulburner. However, Flame manages to take back control out of sheer will to protect his partner. This however causes his own termination. Before vanishing, Flame tells Soulburner he was happy he saw him as his equal and encourages him not to give up, calling him "partner" one last time.
