Naruto the rise of the yokai (female)

Last night I was playing nioh 2 en finishing the boss, which it took me hours to kill him en finish the first part of the story en I was planning to play the dlc too but I was too tired to keep playing. So as I was going to torn off the ps4 but something unexpected happened.

------------------!!STAB!!---------------------

A staff went flying out of the tv end stab my in the chest end sent my flying en landed in my gaming chair I was slowly bleeding out en I was hearing somebody laughing at me en it was coming from the tv as I slowly looking up to see the Tv screen en I saw en old man with red ayes en 3 pupils almost looking like de sharingan laughing at me but suddenly he left the screen only leaving the main opening screen from the game en the only difference is that my avatar is now dead in the Sakura tree the same way as I am.

Now I'm in the interim the world that leads to the afterlife in the game of nioh but why hamura ōtsutsuki was there en why is he offering me to reincarnated in the world of naruto. But my big question is."how the hell a fictional character kill me!!?

I don't own the anime nor the game en I'ven the art
