Dimensional Boundary Contact Prime Field No. 5

was a base model for Saya, Hades: Izanami's vessel.

Appearance
She is a perfect copy of her original, that took the same form as Izanami's vessel, thus they look identical.

History
Five was a huge irregularity created by someone unknown, based on Relius Clover's research, which entailed methods of creating vessels capable of containing even a "god", which Relius learned from Shūichirō Ayatsuki. She was a perfect copy of a girl that existed hundreds of years ago and was consumed by her "brother".

Relius used her as a model for Saya, although he never had the chance to fully analyze her, as she was completely destroyed by Jūbei, he is incapable of reproducing her, with many unknown factors remain regarding her. It's unknown what methods, techniques and processes were used in her creation.

Other Prime Fields Relius built were based on Saya as either back-ups, or research materials, and according to him, Jin Kisaragi and Ragna the Bloodedge can be considered as Five's "children".

Powers and abilities
As a perfect copy, she possesses the same abilities as her original. Among those mentioned were the ability to amplify magic element indefinitely, devouring human souls and taking their power as her own.
