Sara is the loyal familiar of Sex Demon King Shadahl. She's a bird woman who used her magic to reincarnate him.
Sara is a bird-familiar from magical dimension and the loyal servant of the Evil Sex Demon King Shadahl. She aided him in his plan to abduct all the beautiful women of the land and rape them into submission with his sexual magics. Just as his plans for world domination were nearing fruition. The three warrior-heroines, Maria, Eclair, and Miina, discovered his hide out. Before he could win, the three nearly defeated and kill him. It was Sara who saved him in the last second by sending his soul away to be reincarnated. Sara discovered that she had mistakenly mixed a reincarnation spell with a transportation and sent his soul to another dimension to be reborn. She left the dimension find her master on Earth and begin once more.
Her first appearance was in Power Play! Volume 1 CH. 0 "Power Play #0".
Sara shares the same name and character design as the character Sara Saionji from another Yamatogawa created titled Witchcraft. Both are white haired girls with dark skin who wear their hair primarily in pigtails and can use magic. However, the magics they use are vastly different, and Sara Saionji is a human witch with the power of mainly just hypnosis.
Sara eventually found Shadahl's soul reincarnated in the body of a human male on Earth named Sadaharu Imao, but he originally didn't believe she was real. After she gave him a blow job under the table at the restaurant he was in, she discovered that not only did he not have any of his memories or powers, but he was a er-game otaku and a virgin. In a rage, she whisked him outside and stripped all the surrounding women of their clothes and offered Sadaharu his choice to rape. However, he pulled down her panties since he had wanted her. Even with a lack of experience, she succumbed and orgasmed. His personality was still gentle and tender to her. Not the aggressor Shadahl was. She went to live with him and worked to retrain him to use his powers through frequent sex.
Just has she was working on his training, the apartment was attacked by Maria, one of the knights who originally defeated Shadahl. Maria noticed she was alone, and let her take Sadaharu as part of a plan. She followed them in the air and waited for Maria to lower her guard. When she was having sex with Sadaharu, Sara created a living penis of her own and inserted it into Maria's rear. Sara scared off the Pegasus she was using the stay in the air and left Maria no escape. Sara reasoned that maria came alone because she had fallen in love with her master due to the semen she absorbed. She and Sadaharu screwed Maria into an intense orgasm and defeated her.
Sara spied on Sahadaru and Maria as he took her out to the mall for clothes, and she watched them having sex in the changing room. She then turned her attention to Sadaharu's laptop that had all the information of the game he was developing from his subconscious memories of his past life. It listed all the weakness of the heroine, but she couldn't understand much of the otakau gibberish. She then used her magic on the laptop to help Sadaharu defeat the water-ninja Eclair, who came after Maria. This put them all into bathing suits.
Her plans to help Sadaharu defeat these heroines was stopped when the mage Miina sneaked up on her, transformed her back into a bird, and locked her in the cage. Miina used her magic to send them all into Sadaharu's laptop filled with all his sexual desires that he had written. Sara found herself bound and being gang raped by the girls from Sadaharu's previous game stories. Miina's plan was to seal Sara and Sadaharu in the laptop for the rest of their lives with one of the heroines to stay behind to keep Sadaharu drained. Though, Miina left it to Sadaharu to select which heroine to guard them. He picked Sara. He didn't want to let her suffer for the rest of her life being sexually assaulted and tried to convince the the heroes that he could convince her to give up on world domination.
Miina used her magics to alter Sara's memories to relive her first meeting with Sadaharu. This time he was experienced had sex with her right in the restaurant in front of everyone. He was aggressive and nearly convinced her until he suddenly stopped. He didn't want to force himself on someone he cared about. The illusion was shattered when Sara realized she had been tricked. Still, Sadaharu told Sara that he loved women and realized that his phobia had been created to stop him from hurting anyone. He only wanted to be with Sara.
After some discussion with the heroines, more drinking and partying than talking. It was decided that Sadaharu could be trusted not to harm anyone and Sara would stay with him. The heroines left to their own dimension, promising to check in on them. Sadaharu carried Sara, drunk and asleep, back to their home, bt she woke up and found him masturbating to an ero-game. She pulled him into bed to do her instead and do his best to try and make her forget about Shadahl. She went so far as to use her magic to duplicate three Sadaharu's for her to enjoy. She still told him that he'd need to do her another 10,000 more times to make her forget, and he agreed to try his best.
Sara isn't a human but a dark being from another realm and has many abilities that are beyond those of a human. She can not only fly but has many enhanced magical skills.
As a bird familiar, Sara's original form is that of a small bird that can also transform into a human woman. This gives her the ability to fly. However, she's not limited to one form over the other. She also has partial transformation where she can be mostly human with feathers and wings that will enable her to fly.
Sara has a silence magic that can prevent a person from speaking. She used this on Sadaharu to quiet him as she gave him oral sex in a restaurant.
Sara has a magical form of teleportation. This not only allowed her to cross other realms, but she also used it to let her see images from the other side of her teleport. She used this to watch Sadaharu and Maria having sex in a mall changing room. The teleport acts more as a bridge between locations. She doesn't need to step completely into the teleport for it to be active. She can only stick her top portion through while her other half sticks out the other end. This is how she taunted Eclair while still also at Sadaharu's place.
Sara has the ability to cast a magic that can destroy matter with the simple wave of her hand. She used this to destroy a wall where she first met Sadaharu. She can also use this spell to varying degrees. She has used it to destroy the clothes of women in a large area, leaving their bodies unharmed; and it's still powerful enough to break down the armor of the Magic Kings simply my touching it. The armor of Maria pulled apart at Sara's touch like paper.
Another magic Sara has is the ability to manipulate Sadaharu's biology. With this she could keep his erections solid for as long as she wishes. Later, she used this ability to keep Sadaharu ejaculating continuously. These powers were also able to split him into three copies that could act independently as she had sex with all of them.
Sara can use magical energies to form an organic phallus to any size she wishes. She can feel the sensations of this magical-coiled penis as she had anal sex with Maria when she trapped them in the air above the town.
A similar spell was used in conjuncture with Sadaharu's laptop when she unlocked the swimsuit-mode of the game he had based on his previous life. This surprisingly put all of the girls from the game, including Sara, in swimsuits in real life. Sara and Eclair were in school-style swimsuits.
While Sara and Sadaharu had sex with Maria together in the incredibly heights above the city, Sara used a magical spell that allowed Sadaharu to fly so he wouldn't worry about falling. These created impressions on his back of wings and small magical energy wings that floated close to his back.
