Devilman TV AnimeEditIn here she is a demon of the week who captured Miki Makimura and pretended to be her to find out why Devilman turned against the demons. She incapacitates him by slicing his back while in human form so, when he went demon, the wound would grow. After she K.O.s him by blasting him with wind. She uses her antenna to read the mind of Devilman so she would know why he betrayed the Demons(it turns out its because of him falling in love with Miki Makimura). She tries to kill Miki but is defeated and gets away but comes back in Mazinger Z Vs. Devilman and video games.
Devilman OAV/MangaEditIn Devilman:Demon Bird Sirene Sirene makes her appearance almost half way in (despite the fact that she is in the title). She attacks Miki Makimura's house to kill Akira Fudo and sends Gelmer and another demon to distract Akira. After Akira kills them, Sirene catches him in her talons while she is distracted. Akira attempts to transform but her claws prevent it. As she tells Akira of the horrors he will face, Ryo Asuka shoots her below the left breast with his shotgun and she drops Akira as Ryo fires another shot, successfully hitting her in the leg. Sirene fires off her arm to nail Ryo, and Akira transforms into Devilman and fights with Sirene until eventually she summons her arm and uses it to dismantle Devilman. After losing an arm and getting sliced across the torso, Devilman grabs Sirene's antenna with his and jumps as Sirene's own spinning arm impales her in the abdomen. Devilman continues to rip off her left head wing while Sirene is writhing on the ground in pain. She is able to flee for a short period and uses this time to call to Zenon for help. He responds by Kaim and other demons to fight Devilman. Kaim tells Sirene to merge with him despite the fact that her wounds may kill them both. Before ripping off his own head so that Sirene will be the dominate force of the new demon, he tells Sirene that she is beautiful, even after being torn to pieces. Devilman finishes the other demons while Sirene and Kaim come barreling through the forest and electrocute him with their lightning. Charging into him at full force Sirene uses Kaim's horns to penetrate Devilman's body. Devilman pulls himself free with his wings but quickly falls, blood running and his energy draining. Convinced that he'll slowly die from the wounds, Sirene feels at peace and her consciousness fades. Gelmer to get a hostage to lure Akira to her(he gets Miki Makimura). She tries to grab Akira like in the OAV but gets Jinmen instead. After Akira transforms to fight Gelmer, she comes down and Akira is overcome by her soft big DD's. She has Akira in bed and takes a shower when Miki Makimura comes in so they have some time to talk. As Akira is telling Miki why he likes her more than Sirene, Sirene comes in and fights with Akira. During the fight, Ryo Asuka comes in and blows a hole through her when she startles him. She is captured by Baron Ashura and is kept in a box that she can't teleport out of but Ryo accidentally turns it off. After she escapes, she turns down the doctor and is attacked by him in a rebound rage. She confronts Ryo but realizes who he is and he orders her to marry the doctor. She can't bring herself to do it and is unhappy with Ryo being responsible for Amon becoming Devilman. She says she wont do what he says and before Ryo punishes her, Koji Kabuto comes in after blowing up the engine with his BULESTO FAIYA!! Ryo blasts Mazinger Z away with an attack like the one that split Akira in 2 and Baron Ashura tells Ryo the engine is damaged. Ryo says she will face retribution and leaves so she goes off and later meets up with Kaim who brought her arms (like with Rei in the Hokuto No Ken movie where he chucked the dudes arms at him) and they don't really do anything for the rest of the Chibi OAV. Oh yeah. Psycho Jenny tells them to be happy as per Ryo's orders.
In here she teams up with the Getter Robo bad guys and has quite big breasts. She captures some naked chick but drops her after getting her hand zapped by Akira Fudo's Devil Beam. After a meeting with the Getter Robo bad guys they attack and gain the upper hand until Devilman fused with Getter Robo to form the appropriately named Devil Getter. Devil Getter dominates the bad guys until the bad guys fuse into Mecha Demon Shirenu but Devil Getter separates and Akira Fudo pulls Shirenu out of the fusion and grabs her large right breast. After some words with Devilman, she leaves and the manga ends a few pages later.
Sirene is an alternate spelling of the word Siren, the name of a race of supernatural women from Greek mythology who would lure sailors to their deaths by singing. The Sirens are the daughters of the river god and have the appearance of half bird, half human creatures. This has led them to be confused with the harpies who also appear as bird winged women.
