An accident involving a truck brought about the end of humanity. This unexpected event provided Aizen with the opportunity to start a new life in another world.

Interestingly, his destiny led him to the world of Naruto, where he was reborn while retaining all his previous memories.

Until the age of seven, Aizen felt fortunate, although he still did not fully understand the benefits that the mysterious golden roulette would provide him, other than preserving his memories. However, his life was about to take a surprising turn.

A book appeared before him, and upon touching it, a connection was formed. From that moment on, the book became known as [Aizen Kurama's Relationship Book]!
