Not a Ghost

This Fallen Angel seemed weak, as if he was about to vanish. Furthermore, he was chained to the ground and seemed to be taking his strength without any stop.

Vale had seen a messenger before when he tried to summon Lotus once again. They were beings with a hint of divinity with them.

Furthermore, Vale also knew that the Holy Knights, High Priests, and other special Arcanists who had learned the Holy Arts were able to summon such beings to temporarily fight for them.

If the Evanescent Vessels' trump card was having mysterious beings take over their bodies, the Untaintated Sentinels' special move was summoning these beings.

As the fallen angel turned its gaze toward Vale, a sense of longing and desperation flickered in its luminous eyes…

It was as if he just found his savior who would aid him or give him salvation from its spectral prison.
