Spoiling ahead, though if you know the anime, not maybe so bad.
How long does any Apocalypse take? When Volume 11 of this series came out, it looked like it would only take one or two more volumes to reach a certain red-coloured ocean. But nooooooo! Volume 13 ends mid-chaos, and anybody can guess how much more manga yet to come.
This one starts as Asuka is surrounded by Nasties, only for Stupid Shinji to rush in. She shouts that he's trying to show her up by being a hero, but he says he's keeping his promise to Misato to save her. And ya know, for a few seconds, he does. But before either Shinji or Asuka can get out of there, the Nasties are regrowing their limbs and trying to murder both kids as painfully as possible. Meanwhile, Gendo has taken Rei down to where the Lilith giant is, and starts the whole "The time has come" schtick.
Yup, a lot of this will be real familiar to those who survived the original 24 episode TV anime, but the mangaka, Yoshiyuki Sadomoto, has changed a few bits. For instance, in the anime, Gendo says something to Dr Ritsuko Akagi that the audience deliberately doesn't get to hear. In this volume, the speech bubble has actual words, which will possibly spark off yet another debate about whether Hideki Anno intended for them to be what was said in the anime or not.
But hey, you don't read Evangelion for the happy feelings and pony parties. If a unicorn entered Evangelion, it'd probably be swilling down Yebisu beer and spiking little kittens on its pointy horn (and that was needlessly Freudian, so I apologize). But for emo wangsting and disturbed teens, this is pretty evocative stuff. It's anybody's guess when Volume 14 might be released, as Sadomoto has been putting this series out for almost a decade now, and don't hold your hopes for 14 to be where the rollier coaster stops. Just breathe deep and hang on, Eva fans, it'll get there someday.
