During the climax of the massive fight against the Angel Zeruel, Shinji achieved a 400% synchronization ratio with Unit 01, a level thought impossible. However, because of this, Shinji has merged with the Evangelion, and his body has reverted to LCL inside the entry plug. Over the course of thirty days, as Unit 01 stands immobile in its hangar, Ritsuko struggles to come up with a way to restore Shinji. Meanwhile, Shinji's consciousness goes on an introspective odyssey while merged with Unit 01 in which he comes into contact with the soul of his mother, Yui Ikari. After speaking with Yui, Shinji is "reborn" from Unit 01's exposed core. Later that evening, Misato and Kaji resume their love affair. During their meeting, Kaji hands her a chip which details all his findings from spying on NERV, telling her it might be his last gift to her.
