Spiritual Standard Frequency

The Spiritual Standard Frequency 精神基底周波数 (seishin kitei shuuhasuu) is the H-Wave frequency that is unique to each Reyvateil.

In Pureblooded Reyvateils, this frequency is unique to each Triangular Nuclear Loop and is used as the basis for the Reyvateil's own unique FFT Spectrum, which allows to easily identify them. Similarly, this frequency is also affected by the D-Cellophane of each Reyvateil, and it serves as the basis for the formation of their Cosmospheres, assignation of addresses and access authorizations in the SH Server, and the data in charge of their lives' maintenance.

On Halfblood Reyvateils however, this frequency is derived from the H-Waves harvested from their brains for the mirroring of their minds into the SH Server due to the lack of a Triangular Nuclear Loop in their bodies, but it still carries the same purpose as in the Pureblooded Reyvateils.
