One Piece Mirror Sea

In the "Mirror Sea" in the second half of the Grand Line, there is a special devil fruit called the "Shadow Soul Fruit". The eater will split into a "shadow personality" - an independent individual with the same memory and abilities, but with a completely opposite personality. After Luffy mistakenly ate the Shadow Soul Fruit, he split into the murderous "Black Luffy", intending to replace the original body and become the new captain. Zoro and the shadow personality "Ghost Zoro" have differences in their swordsmanship concepts: the former pursues "cutting off fate", while the latter firmly believes that "the one who is cut off is the weak". Sanji's shadow "Devil Sanji" completely abandoned the spirit of chivalry and launched an indiscriminate attack on female targets. Yun Che travels through the world of pirates and has a [mirror copy] system. He can obtain his abilities by killing the "Shadow Personality". As a result, Yun Che fought his way towards the peak of the chaotic Great Pirate Era.
