Why yes, Naoko most certainly does have a cranial input/output jack, skin mounted electrical circuits, artifical lungs complete with a backup electronic voice box, a heavily reinforced ribcage with anchor points for later implants, a bioelectric alternator, and high powered computer systems within her brain.  Plus a utility mechadendrite.<br/><br/>However, if she goes insane, she won't go around calling herself or a member of NERV/SEELE the omnissiah.  That's Ritsuko's job, if the group gets her to tech herself out just as much as Naoko did.  (At the moment, Ritsuko is completely natural, except for her hair being dyed blond to distinguish her from her mother.)
