Ahhh, Yes. The famous "Shadow Doppelganger" technique. Truly, an iconic move of the series.
What? You guys don't remember? From such memorable chapters such as: Chapter...

Well that's not important.
Let's be real for a second. This is one of the big reasons why I have difficulty supporting the "official" releases done by MangaPlus. To put it simply: they're not fans of the series.
They'd rather stick with a shitty translation that makes no sense, than use the one that does make sense, and that everyone already knows.
Did they even bother to look up the etymology of the word before using it? Hell, even if they did, I can still think of several synonym's that are better and would flow eaiser.
Naruto certainly isn't the first series to use the word "bunshin", but's definitely one of the only ones to translate it so retardly.
Tldr; Keep pirating until quality is up to par.
