In this world there was something called bakus, bakus were pets but they were actually electronics they look very much like animals though and they were created by the great Monica herself after a child finishes middle school they are set to buy a baku or else they can't get education it didn't matter how cheap how small how big they needed a baku Monica even gives out level 1 bakus which I should mention the levels there are 4 levels level 4 is the highest level of a baku.
