All awakened seraphs
Silent Wing is an ability that enables telepathic communication between seraphs over large distances using alpha waves「
There is a variation of Silent Wing that Takayama Sou is capable of using which is a communication channel between only two seraphs. The alpha wave usage of this variation is noted to be so low that it is almost undetectable.
Some First Abilities give seraphs their own unique version of the Silent Wing. Bellwethers possess a different variation of the Silent Wing ability that is uniquely their own. When utilizing this variation, massive wings appear above the area in which they are applying their influence on. Similarly, Agitators also have a variant of the Silent Wing that is different from that of a Bellwether's.
The different variations of Silent Wing can be distinguished by their shape, pattern and color.
