TRACE manhwa/webtoon
TRACE: Thirty-some years after the appearance of Traces, humans with supernatural abilities, and Troubles, monstrous beings with similar abilities, a number of people in South Korea were met with extreme difficulties and tasks that had to do with special abilites, especially Sa Ghang Gwon, Kim Yoon Seong, and (Morrienoah) Jin. Involved with those three were Han Tae Eun, Pierrot/Jeong Hee Sub and his team of Traces, the K4, organization Hanjo, and God's Virus, among others. All of them, separately and together, played a huge part in how the world saw Traces, which is neither an entirely good nor a bad thing.
TRACE 1.5: Communicator: Han Si Hyun of the N.I.S/National Investigation Service based in South Korea had rather extreme ideas. Among people like the N.I.S's Officer Lee and the conservatives who supported him, Si Hyun's suggestion that humans and Traces should try to communicate with rather than exterminate Troubles was met with disagreement and outrage. As such, the so-called "druggie" Han Si Hyun took matters into his own hands and, throughout tons of controversy and with the not-entirely-willing help of his assistant, Sun Hee Ji, a friend named Han Tae Hyun, and a school girl named Jung Eun, he sought to communicate with a Trouble he named Sarang.
TRACE 2.0: Armor Line: The main characters of 1 and 1.5 were still in the news, but the biggest thing in Korea at the moment was a small group of murderous Traces called the Swindlers. As the Swindlers made a game of shooting up human police stations, and Trace drug dealers cost civilians their lives, a police officer named Suh Bum Gi was desperate to prove the worth of normal humans in a world full of deadly supernatural beings. Everyone who had lived during he past thirty years had probably questioned why Troubles and Traces existed and why they killed, but those questions were always on Officer Suh's mind. As he got more and more involved with the drug business, Trace organizations, and the Swindlers, the answers seemed clearer and more dangerous than ever.
