Robot Girls Neo

The anime Robot Girls Neo takes place in a post-disaster Nerima, where a photon energy disaster allegedly occurred, but the extent of the damage is unknown. The area is now dominated by the remnant photon research facility tower. Z-chan and Gre-chan reside in the Shutter District, at the base of the tower, in a house made from salvaged materials they call Photon House. The house relies on a previously efficient photon energy source, despite the current Getter Rays that fall from space.
