One Piece: This Era Is Called the Fire Dragon

【Mythical Zoan + martial arts + slow burn + fiery action + fire dragon + no System】 He is the world’s greatest criminal, trampling all justice beneath his feet. He is an unyielding seeker of light, the only light in the darkness. He came from hell, so he pities the people of the world and leads a band of sinners. He is the son of a CP0 chief, yet he massacres the Celestial Dragons and sets fire to Mary Geoise. He places huge bounties on the families of the Marines, making them taste the bitter flavor of “justice” for themselves! When he stands at the top of the world, this era will echo with his voice. “Wretched people of the world, welcome to the bright new world promised to you by the Fire Dragon!” (P.S. It’s a pirate story. The writing is a little rough at first, but the exciting and thrilling parts are coming. It takes off in Chapter 21, and Mary Geoise goes up in flames in Chapter 29.)
