One of the main characters is a police investigator , and this character is completely ripped off of Zankyou no Terror. Other two characters are basically Zero two and Hiro for Darling in the FranXX.
In the anime there is advanced technology (some more advanced than ours) , yet they all drive 50's cars.
At the end barely get to see the characters after all the chaos.
It's not a bad anime but it isn't a great one either. Watch it only if you ain't got any better anime to watch.
