Reborn as Kakashi

Hey there are his is my first novel/fanfic so please cut me some slack! . . . Our mc was killed and reincarnated into the body of Kakashi hatake with all of his previous memories. Will he die in this world of Shinobi or will he go down in legend as it’s protector. No harem! No system! Actual training involved in him getting strong. oh yeah and a shinigami who knows nothing about human emotions is talking to him inside of his head
