Shiro elevator

The Reinforcement Elevator was found inside the Shiro Sanitarium. It was used to either transport infantry units to send reinforcments against Yuriko Omega (and worked much like an Instant Dojo), or by Yuriko herself to reach Izumi's room. One notable fact about the Elevators was that when Yuriko came back to the Sanitarium for the second time, there were four elevators leading to Izumi's room, and Shinji Shimada destroyed 3 of them to prevent Yuriko from reaching the room, but he didn't destroy the fourth elevator because if he did, he would have been buried there for ever, since there was no other way to get back.
