The Prayer song plays as a important plot point during the story, where Sera's is known of singing the song. However, when questioned why would she know how to sing the song, she replies that she has forgotten due to amnesia. Following the events where the citizens of the Junkyard realizes their insatiable hunger of devouring others, the prayer song is revealed to be able to suppress the Junkyard citizen's insatiable hunger, and with that, they can co-exist peacefully without the urge of devouring each other.

Sera would later sing the Prayer song to sooth Gale from succumbing to his hunger, she sang the Prayer song again while Serph, Heat, and Argilla was out negotiating with the Maribel tribe. During this time, Gale encounters a hallucination of a person resembling him, apparently dying with a women beside him crying. The Prayer song later plays a key factor of defeating the leader of the Brutes Tribe, Varon Omega. Using the inherent technique bestowed by Angel, Hunger Wave, Varon transmits the hunger signal, forcing the members of the Embryon succumb to their hunger. It was eventually healed by Sera, via the Prayer song.

The final boss, Hari-Hara is also capable of using the Hunger Wave ability, which can also be cured by Sera's Prayer Song.

Digital Devil Saga: Avatar Tuner 2
Following the events of Digital Devil Saga, it is later revealed that the Junkyard is in fact, a training stimulation to create the most powerful AIs, whereas the Nirvana is the real world. In the real world, the Black Sun rays plagued humankind with a disease, turning those who came in contact with the Sun rays into stones. The disease was eventually known as the "Cuvier Syndrome". Only those who have been inflicted with the Atma Virus can wander around safely under the exposure of the Sun.

Due to the fact that humans who have been inflicted with the Atma Virus can wander safely under the Sun, Margaret Cuvier, the chief command of the Karma Society eventually reveals her plans of turning everyone into Atma Demons, while keeping Sera stasis inside the EGG facility so she could sooth the citizens' insatiable hunger via the Prayer song.

The hallucination Gale had been encountering is later revealed to be David, a scientist of the Karma Society. David also shares a close relationship with Jenna Angel, whom he loved. Unfortunately, he caught the Cuvier Syndrome and was in an isolation ward when it was attacked by terrorists. With his dying breath, he sung the Prayer song to Jenna, and implored Jenna not to hate humanity for what they had done. His data flowed into the Junkyard, and into the body of AI Gale.

In the reminiscence of the isolation ward attack, David had been singing the Prayer song to Jenna Angel right before his death. Jenna may possibly be the one that taught Sera the Prayer song.
