Twin Succubus (双子の小悪魔 Futago No Koakuma, eng. The Twin Devils) is the ninth UMEMARO 3D mini-movie collection, released on December 27, 2008.



"Private school Yo-mei Gakuen is financially being dependant to the fund which school principal and his follower provide. By using their power, the principal and his follower take an advantage of their position, requesting young students to be their sex toy. Today, some more innocent students are being sacrificed..."


The game opens with Ohara berating Chokugen for his school's poor financial performance while Mimi stands by and watches. Hosokawa then implores Ohara to move on to the 'main event', revealing that they are both naked. Chokugen brings in two girls, Kamira and Kurusu, as Shinnosuke explains in voice-over dialogue that Ohara and Hosokawa have Chokugen bring girls in from the school every night so that they may rape them. The girls are hypnotized by Mimi so that they do not remember their ordeal. Ohara turns to Shinnosuke and offers one of the girls to him. The player chooses the girl they want, and she and Shinnosuke have sex, while Ohara and Hosokawa double-team the unchosen girl. The player has the choice at two points in the game to shift the focus to Ohara and Hosokawa, or remain with Shinnosuke.

With Ohara and Hosokawa, the unchosen girl is double-teamed by them, first through oral penetration, and then through double penetration, in positions that differ depending on which girl is being seen. As Ohara and Hosokawa climax, the girl's mysterious powers take over, and they find themselves unable to resist their essences being drained.

Once Shinnosuke climaxes, the unchosen girl comes over to them, and Kamira and Kurusu proceed to simultaneously have sex with Shinnosuke, though the player has the option to choose which girl to primarily have sex with. When he climaxes again, he begins to pass out, and it is revealed that Kamira and Kurusu are succubi, draining his life force. He catches a glimpse of Ohara and Hosokawa's corpses before falling unconscious.

If both paths have been taken, the game's ending will be unlocked. Shinnosuke awakens shortly after passing out, to see that Kamira and Kurusu have completely abandoned their human disguises. They have sex with him again, this time presumably draining his essence completely.

The next morning, Chokugen is seen sitting in the chair that Ohara resided in, his foot on Ohara's lifeless head. He smiles in a sinister manner as Mimi watches the sunrise, implying that the night's events were orchestrated by Chokugen.


Twin Succubus introduced and re-introduced several characters that would become major players throughout the OMEGA saga, most notably Chokugen and Mimi. The game retains the interactive format introduced in Lewd Consultation Room, having the player choose between Kamira and Kurusu in the beginning of the game and after a set of scenes with the chosen girl, as well as giving the player the option to switch between Shinnosuke's scenes and the scenes with Ohara and Hosokawa.

The game received an English subtitled release shortly after its Japanese release, and also was given a full English Voice Version, the last UMEMARO 3D release to date to receive this sort of treatment.


  • Twin Succubus introduced more characters than any other release to date, with five.
    • Ironically, three of those do not recur in a future release, the most of any release in the UMEMARO 3D canon.
  • Mimi Minami's re-introduction here is the first of three consecutive appearances in UMEMARO 3D releases for the character, the longest streak of anyone in the UMEMARO 3D canon.
    • Mimi's re-introduction is also the first time a previous character has appeared in another UMEMARO 3D release since Sasa's appearance in Mai. She shares this position with Shinnosuke.
  • Strangely, despite Lewd Consultation Room's English Voice Version being released just two months after its initial release, Twin Succubus's English Voice Version was not released for a year and a half after its initial release. It is not known what caused this lengthy delay.
