Rest In Piece Kakashi Hatake

I don’t watch anime can some on explain this to me

This is from Naruto. The dead guy (i think he comes back to life) Kakashi is shinobi which u wouldnt know. But everyone loves Kakashi because he's calm and is always happy. He reads books about women though

ok so yes this guy dies but than he gets revived

He died but then he got revived.
