One Piece: I Reincarnated as Ace with a system

Kiniro was born with the ability to see the sins of others and to feast on them. Many believed this to be the ability of a savior with the possibility of saving their damn souls from the pits of hell. Kiniro never believed it himself, but was fine with misleading those who depended on him. They weren't exactly the innocent type. However, he could never have expected the true origin of his abilities, or that there was an entire society full of people with powers similar to his own.

What is a monster? Humans normally define monsters as fear inducing, bloodthirsty creatures bent on destruction. But to Noah? Monsters were the humans who despised him without justifications, who taught him to loathe himself just for being human. Life was hell, a hell that was surrounded by “monsters”. Until one day, the world changed. Humans were suddenly graced by a Divine voice, one that warned of their extinction, but also promised them power. They were bestowed with a system, a system to aid their fight for survival, to survive against monsters. And when humanity was given that chance to survive, Noah chose to walk a path of a tamer, to befriend the very monsters that were threatening the humans' extinction. As he tamed the monsters, learned from them, bonded with them, shedding the last remnants of what it was to be human. Noah began to wonder, is it wrong to be considered a monster? Feedback is definitely appreciated, good or bad, let's make the story good together. I would like to note that the main character isn’t completely ruthless, he's more chaotically neutral. There’s a lot of good stories out there with ruthless, bloodthirsty, cold hearted main characters so if that’s what your interest in then I’m sorry to disappoint you.

(No CP, All-Encompassing Charm, Brotherhood, Invincible/Roleplay/With Secret Identities, Massive Private Settings) ​ Because he complained about Satoru Gojo’s character assassination in Sukuna Kaisen, Jiang Wu was selected by the System to accept a roleplaying mission. He stepped into the world of Detective Conan wearing the shell of Satoru Gojo. While trying his best not to go OOC (out of character), he must obtain 100,000 Impression Points from both the Black and Red factions, plus 1 billion Popularity Points from readers in another dimension! ​Although he is the legendary man who remains "in character" no matter how he’s written, roleplaying him isn't easy, but... ​"I'll win. It's the same no matter who the opponent is." ​Satoru Gojo, leaping between the Red and Black factions, is the Great Demon King who can go shoulder-to-shoulder with the Black Organization’s "Model Employee" (Gin); he is the genius Head of a Shinto family; he is the "White Moonlight" that the Police Academy Five can't get over; he is the eccentric guardian of Kaito Kid; and he also moonlights as a black-bellied, cat-headed Great Detective who makes Conan feel inferior! ​Satoru Gojo’s marvelous adventure in "Conan-Science," now officially serializing. ​The pace of this article is relatively slow; it will start from Satoru Gojo's childhood in the Black Organization arc~ The protagonist is "Grey" leaning towards "Red." Once the official Conan plot begins in the later stages, there will be "Manga Forum" segments. [Note - This is a translation. For Adv Chs join my Patreon]
