One Piece: Ulquiorra Cifer Template

Ash reincarnated in the world of One Piece and became Rocks' younger brother.

Ash, who possesses the Ulquiorra template, was besieged by many strong men on the island of God Valley because of his strength, which was so strong that everyone feared it.

Fortunately, with the system's help, Ash escaped from death and fell into a deep sleep. The World Government collected Ash's body and put it on the unknown seventh floor of Impel Down: Devil's Nest.
