Emma was born in an orphanage.
A strange orphanage. Children in the orphanage are not allowed to leave the house until they are twelve years old.
This year, Emma, who turned twelve years old, was sent to school by her mother.
Then Emma suddenly discovered that the children in the orphanage seemed a little different from others.
Because normal children will not have numbers printed on them.
They are like guinea pigs.
In order to pursue the truth, Emma and her friends embarked on an adventure journey.
PS:
The modern background refers to the private setting of the original work, and no spoilers are allowed when it comes to the plot.
I will add more as I think of the above.
