The Manifestation, EXS(Exist) (顕現(イグジス)) is the source of an In-Birth's power and what Voids seek to consume. Based on comments made by various characters, it appears to be a form of energy present in all earthly matter, described as "the source of all things".


In-Births are capable of using the power of Manifestation to give the EXS stored within their Vessel a shape, in the form of an EXS ability; In-Births that possess EXS also have their physical abilities enhanced to a degree, as elaborated by Tsurugi in Phono's chronicle mode and shown in Chaos' chronicle mode, which is likely enough for them to at least manage their powers. Overuse of EXS abilities or gathering huge amounts of EXS within their Vessel however, can cause an In-Birth to lose themselves and start to become completely different, showing personality traits such as increased bouts of rage and violence. Soon, this turns them into a Void.

Voids are driven by instinct to consume EXS and can manifest themselves in the presence of large concentrations of it.

The Abyss at the center of the Hollow Night produces an endless amount of EXS, attracting Voids as well as In-Births seeking to gain further power, and possibly even the status of a Re-Birth.

It would also appear, based on story dialogue, that characters from other universes such as Eltnum and Akatsuki do not require EXS to use their abilities, though they still contain it within their being and are thus, vulnerable to consumption by Voids.


The FLS(False) (虚偽(ファルス)) is a power used by Voids and Autonomic Nerves to fuel their abilities. In order to use FLS, a Curse Commandment is required.

Currently, Merkava and Vatista are the only playable characters to make use of FLS rather than EXS. Kuu is also known to use FLS.
