In 2012, the Earth is besieged by monstrous, gigantic aliens, against which a mecha project named Devadasy, developed by international organization SPIRITS, is the only possible defense. Said mecha units can only be piloted by pairs of teenagers, and are directly powered by the pilots' sexual energy and feelings. This is what bored 16 years old Kei Anno finds when he leaves Tokyo to enlist in SPIRITS along with childhood friend Naoki Matsudo. However, upon arriving, he also meets a mysterious beauty with blue hair and dark skin, Amara Minakushi, whom he feels a powerful connection with. Kei and Amara would pilot Devadasy together in order to fight off the menace and discover some ancient secrets.
Any similarities with Neon Genesis Evangelion are certainly not coincidental.
An OVA adaptation was produced along the game and released some months later. It's a Compressed Adaptation serving as a prologue to the story.
Devadasy provides examples of:
- Body Horror: The nanomachines in the OVA. They seem to simply cover the female pilot's body at first but it eventually becomes clear that they're actually being infused into them and the metallic parts are literally growing on them. And the longer this goes on the more elaborate and mechanical the parts become. In the final part of the OVA Amara is practically fused into Devadasy from the process.
- Compressed Adaptation: The OVA series. The game's obscurity makes it difficult to know, but it rumoredly only adapts a sixth of the game's content.
- Deus Sex Machina:
- The Devadasy mecha is effectively powered by libido, and it's implied the alien mecha also draw from their human hostages' attraction to other people.
- Apparently, the only way to analyze the concentration of nanomachines in human sperm, which makes Dr. Takashina seduce Anno to obtain a sample.
- Innocent Fanservice Girl: Amara in the OVA has little issue with being seen naked by everyone and in fact pilots Devadasy nude.
- Meaningful Name: A devadasi is a female temple attendant in Hinduism, who in some areas and times served as a sacred prostitute.
- Painful Transformation: Played with. The nanomachines that cover the female pilots aren't meant to be harmful and instead are meant to stimulate them for energy output but they still find it unsettling and it's shown become more physically distressing the longer the process goes on. It's also shown that being too active is bad for their health as Amara goes into a Heroic RRoD after the first battle in the OVA and can't pilot again until the nanomachines are removed.
- Rei Ayanami Expy: Amara, an Artificial Human with a stoic personality, blue hair and a weird origin.
- Shout-Out: The series is a Whole-Plot Reference to Neon Genesis Evangelion, to the point it would be easier to list the differences rather than the similarities. In any case, and for starters, the main character is named Anno of all things. Interestingly, however, Amara is not solely a Rei Ayanami Expy, as she also combines elements of Nadia from Anno's previous anime Nadia: The Secret of Blue Water.
- Walking Swimsuit Scene: Naoki wears a one piece swimsuit when she pilots Devadasy.
