if i remember correctly, in japan they don't have this thing called ''child protection'' or something, i dont remember the name xD
but anyway, that would explain it a bit isn't it?
@RedSkyX2 You are remembering wrong. Japan has child protection laws (including regulations that parents can lose their guardianship if they abuse their children) and services.
However, if the author had it done realistically the manga would stop even before chapter 1 starts.
