Marineford War: I Will Stand in the Sky

During the Marineford War, a sharp blade suddenly pierced through the chest of Fleet Admiral Sengoku from behind.
Amidst the utterly shocked gazes of countless marines and pirates, Vice Admiral Yann, the "naval hero" who was always lazy and gentle and called himself "Buddhist," withdrew his blade and his figure gradually floated up into the air.
"The eight-hundred-year history of the World Government throne being empty is about to end, and from now on I will stand in the heavens."
With an utterly calm expression, Yann looked down, silently declaring his presence.
'certainly……'
'From this day forward, all evil in the world will be in my hands!'
