Machine God: Nirvana

Deus Machina: Nirvana is a form of automaton. Has 195cm in length. Ada Clover's body was used in her creation. With time, Relius Clover created something similar to Nirvana. That's Fluctus Redacium: Ignis, Ignis Clover's body was used in her creation. Nirvana is a transcendent state of enlightenment and tranquility in Buddhism, and Deus Machina is a latin phrase meaning "god machine".

It is suggested that Nirvana is not a combat Nox Nyctores, or at least not on the same level as others. Hakumen told Carl that Nirvana was never meant to 'dirty her hands'. Rachel also informed Carl that Jin and Noel's Nox Nyctores' were more powerful. This does not mean Nirvana is not strong, Nirvana when teamed with Carl is a very strong fighter injuring many strong characters throughout the series.

Nirvana has displayed several fighting techniques. Nirvana is primarily a melee weapon, on Carl's orders she will either punch, throw or stab an enemy. Her hands appear to hold some form of blade that is her man method of attacking. She also has the ability to teleport, shown in combat teleporting to Carl at his command or teleporting Litchi and Carl a fair distance away from Relius. Nirvana also holds a powerful bomb which is Carl's Astral Heat.

Nirvana's affect on Carl's mind has been a very debated subject in the game. According to Litchi, Tager and Hazama it inflicts madness on it's owners mind or possesses them. While Hakumen stated that Nirvana is driven by it's owners killing intent and that others are just trying to shift the blame. It is unknown which is true.

Nirvana has also shown signs of protectiveness over Carl even when Carl is not commanding her, further strengthening Carl's belief that it is Ada and not Nirvana. She has protected him from deadly blows, despite Carl pleading for her to not protect him. She has also hurt Noel and Bang when they proceeded to touch Carl despite their harmless intent. Wheter this is because of Nirvana holding Ada's sisterly affections for Carl. Or Nirvana simply protecting her master is unknown.
