You try ordering a new robot, but instead you get Kasane Teto?

Basically Chinamini_Sato's song, Adachi Rei, if Teto survived and got shipped to your house.

There wasn't much to go from the song, so my interpretation is that Adachi Reis are a new trending form of robots due to their intelligence and ability to do anything. You can order one, and it'll ship to your house.

I hope you enjoy this bot!
