Review Detail of Tafara in Reborn as Naruto's Twin Brother

Author never re read his own work. There's a lot of mistake everywhere. I wonder about it, did his finger is so big that he can't use the normal keyboard or something. Or did his backspace is gone wrong or something. I don't know. The story is decent, but athor unthoughtful writing is bother me a lot. Is he really at 5 lvl reader? Did he never annoyed by other writings that he doesn't even know his mistake. I am disappointed.
