The Akuro Akuro no Mi is short for Akurojin-no-hi Akurojin-no-hi no mi. The Akuro Akuro no mi is a devil fruit that gives the user the ability to produce the legendary Akurojin-no-hi flames. These fires do not burn you physically but burn away at you spiritually. Anybody who does not flee from these fires will become gravely ill and in many cases die.
