Naruto: Survival First

A corpse in Orochimaru's laboratory was resurrected, turning Orochimaru's failed experiment into an incomplete semi-finished product. In this way, a soul that has lost its memory has settled in this experimental body. Even if it has forgotten everything, even if its life span is only a few years, the instinct that seems to be engraved in the soul is driving her to constantly struggle to survive. (The timeline begins with the end of the Chunin Exam and Sasuke's arrival at Orochimaru's place.)
