Haki is the potential power possessed by all humans in the pirate world. This power is an innate ability! However, the vast majority of people are not aware of this power, or they are unable to exert it throughout their lives!
The number one killer in the underground world, "Yakami", accidentally came to the world of pirates where there are many strong men, and gained the ability to practice domineering like a plug-in. From then on, he returned to the sea like a dragon, entered the mountains and forests like a tiger, and embarked on a path belonging to the overlord!
