When Himiko's body is discovered, Vogel and his men try to take away her but she suddenly stands up and gives everyone a jump scare.

It can be seen that there is a contraption under Himiko that supports her body to sit up.

I cannot think of why there is a contraption under Himiko's body.

  Any ideas?
