He is the master of six kingdoms. As long as he wanted, his cavalry is ready to wipe off any country.

This is the story where Urahara Kisuke died after Nel failed to save him inside Askin’s Gift Ball Delux and reincarnated in the world of DxD.

I am not sure if I can capture Urahara’s character properly so I apologize in advance if you are not satisfied.

Also, English is not my native language.

I don’t own any of the characters from the canon.

Jacob Steve, an Old Man, died at 116 after living a whole life.

But Jacob always had a dark side, which he always suppressed and hid from others.
However, in the later years of his life, when death was inevitable, he understood there wasn't any point in having wealth, knowledge, or desires if you couldn't have a life to enjoy them.

He became obsessed with fabled immortality and devoted his reaming life to extending his fleeting lifespan, but just like any other failed.

However, he mysteriously got another chance at life and found a way that led to fabled immortality.
But he was also forewarned that the way led to it was filled with blood and darkness!

In the end, Jacob chose it anyway with no way of going back, and it was also the start of his suffering and his icky, brutal journey toward the 'Immortality' he wanted so badly!
