"A spirit mimicking a human wearing a Demonica. It cannot speak, but it seems to be able to understand your will and acts when ordered. It is thought to be part of the "Spiegel Effect" of the Schwarzwelt, which mirrors the real world."
—Shin Megami Tensei: Strange Journey Compendium
Demonica-L, Demonica-N, and Demonica-C are a special, password only demon appearing in the game. It can be initially summoned using a special password. The letter in their names following Demonica, 'L', 'N', and 'C' denotes that it is of the Law, Neutral, and Chaos alignment respectively.
Unlike Demonica-L and Demonica-N which resemble the Demonica suits of the Schwarzwelt Investigation Team, Demonica-C is the only one of the three Demonica demons with its own color scheme. In its case, it mimics a human wearing the Demonica model used by the members of Jack's Squad.
