Naruto : The Sword God

In the World of Naruto , where Strong thrives and weak dies . A modern earth Scientist Reincarnates as Hatake Kirito Follow his journey as Big boss behind the scenes Why Big boss behind the scenes because this isn't a Chinese novel in which protagonist gets golden fingers (or so they say) and gets ridiculously OP and becomes boss this is Down to earth novel with realism. Love intrest - Tsunade -100%, Temuri mei- 45% and I don't know about anyone else hopefully in future.
