In the manga, upon taking over Goro's body and developing his own consciousness, Satan, at the time known as Rinka was described by Yuri as being like a very powerful baby. He lacked any any real moral compass and had no concept of right or wrong, thus he did not comprehend the moral ramifications of killing and wanton destruction. Despite this, he clearly cared for Yuri. She was the only one he would listen to and he was shown to be immediately jealous upon meeting Shiro. Satan was also shown to be extremely competitive, attempting to kill Shirou after losing a game to him and vowing to beat him. He also had an incalculable intellect as he learned at an accelerated rate.

After gaining a more awareness and developing an ego, Satan gained a god complex, after realizing he was smarter and stronger than any human and demon alive to the point where he'd kill anyone around him or Yuri. Despite this, he maintains his obsession for Yuri, to the point where both of them made love, which resulted in her conceiving a child, however without his knowledge of the latter. At the "betrayal" of Yuri, which was Lucifer attacking him while Satan was in a weakened and erratic state due to his Goro body breaking down, resulting in his hatred toward his former love and his current mindset.

BIOGRAPHY

Record of Satan's existence is actually quite short, with his ego only sprouting a few years before the Blue Night. Before, he appeared as nothing more than small specs of blue light, and was called a "Rinka", along with many other names depending on region. He would randomly appear around the world with no reasoning, thus causing many to have different interpretations of him. Many different descriptions of a Rinka included dead souls, the fires of hell, fairies, and temporary forms of sacred foxes. During this time, Rinka had no conscious.

Rinka was first fully brought into Assiah roughly 19 years ago. His ego sprouted into the strongest clone the research facility made, that clone was meant for Lucifer but unbeknownst to the other Demon Kings, they had no idea who it was that possessed the body meant for Lucifer. By the time they realised, it was too late. Rinka escaped the facility and quickly found Yuri. After being taken back to the facility, he was looked after by Yuri, as she was the only one he would listen to. Yuri would being him books and toys, but after 1 year and 3 months he started becoming bored with them. In an attempt to expand how world view, Yuri brought Shiro along with her to play with Rinka. The demon was immediately distrustful of Shiro and grew to hate the exorcist quickly.

The next day, Rinka took a guard hostage and demanded to be given more books for the guard's safety. After several hours Yuri approached Rinka in an attempt to convince him to let the guard go, only for the demon to nonchalantly kill the guard and explain to Yuri that he had come to the conclusion that he was the Demon God Satan. Fleeing from Section 13, Satan was in hiding for at least sixth months before his body began failing, prompting his return to the Asylum.

After a month long siege, Yuri returned to Satan's side, during which time the Okumura twins were conceived. Attempting to flee from Asylum, Satan's body finally gave out, leaving him crippled until the Blue Night; About nine months later, when Yuri Egin was giving birth to her children and the mass slaughtering of exorcists around the world took place.
