Sayaka had androphobia (a severe fear of men), but it doesn't occurred around Kamina because of his kindness, that made her fell in love with him. She is an impulsive person and will try to protect those who are important to her. She becomes shy around Kamina prior becoming insane.

At first, Sayaka is portrayed as a sweet girl, gentle, kind, and a loving girlfriend with Kamina. When she became insane with the Russian Sleep Experiment made by Hiragi Kureto, she became sadistic, homicidal and insane. So much so that she tried to have Azul Jissele kill herself in order for her to be the new ruler of the world. When insane, she wanted to "tie the knot" with Kamina and mix their genes to make a new world.

Meta Artificial Demon
Meta Artificial Demon is the name given to people who doesn't become completely Artificial Demons, they just became insane and evil like a demon but are not 100% demons. Sayaka, like Eckidina, is strangely willing to indulge the whims of her inferiors, and is quite personable with those loyal to her, and is similarly ruthless towards her enemies. However, she is individualistically cruel and sadistic, brutalizing and maniacally taunting Azul and tearing Natsuki's heart out simply to make a point. She enjoys domination and control, lusting for power over the world in order to give it to the her.

Artificial Demon
She is more than ruthless and manipulative demon, she is vile to the point in becoming a devil by using her beauty and love feelings for her boyfriend to manipulate him, as such he uses her manipulative streak to recruit many followers, including new ones. Sayaka has also been shown to be very cruel, shown when she looks down at a defeated human and only says that human was "useless" and when humans die they become "trash". While she is tremendously powerful in her full Artificial Demon form, she is also shown to be psychopathic, having no care for the consequences of her actions, and exposes one's weakness on a psychological level for her own personal gains.

Background
25 years ago, 5 years after the First Spacequake, she lived with her parents in Osaka where she first met Kamina when they were kids. After her mother's death, she was left alone with her father and Kamina. Sayaka had androphobia, the fear of men because she was bullied by boys of her school many times. However, Kamina was different and saved her many times until she fell in love with when they had 15 years old and she became his girlfriend.

At some point, Sayaka and Kamina joined the KnightWalker Funeral Parlor to fight the KnightWalker Family. However, 5 years after they joined the KFP, Hiragi Kureto took interest in Sayaka and captured her turn her into a Artificial Demon by using her as a guinea pig in the Russian Sleep Experiment. However, Sayaka escaped but lost her sanity and would eventually turn herself into a demon.

2 years later, Sayaka dissapeared and became obsessed with the Tech of the End that Hiragi was trying to do, and tried to create her OWN Black Demon. At some point, Sayaka kidnapped 20 infants and tried to fuse the Magi-Tech of the Tech of the End with the babies, however, 18 infants died in her experiment and only 2 of the infants survived the experiment, however, before she could put the experiment into practice, Hiragi located and sealed Sayaka in a demonic weapon. And so, Sayaka turned an Artificial Demon, in other words, a AD. However, Hiragi never located the two babies that Sayaka used as guinea pigs. The babies were Haru Zageko and Revy.

Days later, Kamina couldn't leave her and took her as his Demonic Weapon, however, Sayaka used his feeling to manipulate him to bring the Black Demons to her; Haru Zageko and Revy.
