Disclaimer: I don't own Naruto or Bleach

Plot:

Naruto dies and loses his chakra but gains Reiryoku, along with the ability to manipulate Reishi. The world changes and hollows start to appear, eating people. Naruto protects those he can from hollows while trying to keep the inhabitants of Hell from influencing the world.

Key Points:

The story takes place before the Three Worlds came to be and the Soul King came into existence.

Naruto is a soul with powers not officially a Shinigami, but his powers resemble a Quincy and Shinigami.

Naruto is the founder of one of the noble families in Soul Society.

Naruto befriended the Soul King, and after he was sealed and dismembered, he separated himself from the Soul Society and became a hermit because he was disgusted by their actions.

Naruto doesn't have a Zanpakuto but he can create weapons like Quincies.

Naruto gains the ability to subject Reiryoku and Reishi so he can control, absorb and manipulate them at a subatomic levels.

Pairings can be sing or Harem.

AN: I just noticed how much influence Bleach took from the bible beside Yhwach, Ichibe is basically Adam and Soul king is God, there is much more.
