Headscratchers / Kikaider

• When Rieko dies, what is stopping them from simply repairing her, instead of just burying her parts?
  • Either the damage is worse than presented, or there's no one the heroes can contact to fix the damage.
• In the manga there's a scene where Mitsuko has Jiro take off his clothes so she can search the gaps in his mechanisms for the Jeminy circuit designs, and he appears to have fake skin covering his whole body, except his hands, which were shown earlier to be just bare metal beneath the gloves. Why would you leave the hands metal if you were trying to make a robot that could pass for human?
  • Mitsuko tells him to keep his underwear on during that scene, implying he has actually has something under there she doesn't want to see, which makes it even more odd that his hands were left as is. Huh??
