Death Guns in the Higher World - Chapter 3: Nursing Alex

A world where magic beasts went extinct… until technology revived them!David wakes up in the middle of a Hatching Ceremony in the body of Jethro Merrick, clutching the lowest ranked egg.Now he’s living the life of a poor mechvet’s son, dreaming of adventure as a Riftwalker (think monster taming and dungeon clearing… but with cybernetic beasts!).But dreams crash fast. His egg hatches into a Red Lizard—cute but powerless and only used for pest control. Just as Jethro resigns himself to a boring life, a wrong turn during a Rift Training expedition lands him in a forbidden Rift zone.He barely escapes alive… only to wake up with a supercharged power: he can see the magic and mechanics of every mechbeast, right down to their origins!Here’s the catch: the ancient conqueror who once had this power wants it back, and he’s bringing an army of terrifying mechbeasts to take it.To survive, Jethro must build an army of his own, starting from his powerless frail lizard. But can a pest-control pet (and its rookie human) save the world?Let’s hope so, because our dear world of Nebulon desperately needs saving!

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.
