RE-TAKE is a 6 volume Evangelion unauthorized doujinshi; it is generally considered to be one of the best Evangelion doujinshi, and is elaborately produced, with an official soundtrack (OST), a trailer (of a hypothetical animated version)[1], and a re-release which omitted the hentai material for an all-ages RE-TAKE.
Plot
RE-TAKE tells the story of an alternate universe; the point of divergence from the TV series is episode 16, "Splitting of the Breast". When Shinji Ikari recovers from his captivity in the Dirac Sea, he is haunted by a bandaged version of Asuka Soryu Langley that only he can see; she constantly abuses and verbally torments him. Shinji has memories of the canon events from the TV series; further, he recalls many of the events of End of Evangelion, as does the spectral Asuka (who hates this Shinji for abandoning her to be attacked and killed by the mass-production Evas). Remembering the many horrifying canon events, Shinji strives to use his foreknowledge to prevent them and bring about happier endings. The plot continues on in a complex multiverse, finally reconciling Shinji & Asuka.
Publication
In order of chronology, the volumes are 1, 2, 3, 0, 4, and After. Books 1 and 2 were released in 2004, books 3 and 0 in 2005, and the 4 and After in 2006. Kimigabuchi also released a minor hentai doujinshi, RE-TAKE 1.5, but it has minimal connection to the other volumes.
There have been no official English releases, only unofficial fan scanlations.
