Shin Seiki Evangelion: Koutetsu no Girlfriend 2nd

In this alternate retelling of Neon Genesis Evangelion everything is different. Shinji and Asuka have grown up together as childhood friends, Rei is the new kid at school, Misato is their teacher, NERV is just beginning to assemble teenagers for their experiments, and the second impact never happened. The story proceeds as a romance rather than an action series, with love triangles a-plenty.
