This show is definitely very much similar to Pacifistic Rim where humans right an alien in a robot suit, but the difference with this anime is it almost feels like the character is connected to the robot, but at the end of the episode we see the robot is actually alive? Idk if I saw that correctly but when the mask of the Eva broke an eye appeared. I am getting more intrigued to figure out what happened 15 years ago with a similar incident that made the city go under. Then as always gov't has to play a role which some level of corruption.
