Sleepless Night Hunter

There are two kinds of light in this city. One is neon and the other is knife light. Neon lights illuminate Tokyo for everyone to see, and the light of the sword only flashes in the dark. The man carrying the knife is codenamed K, and he is not in any files. He only does one thing - hunt those who do evil under the neon lights. They are called the "evil party" and have penetrated the blood vessels of the entire city. They thought they were hunters. Until they find themselves prey. And a criminal policeman goes deeper and deeper on the road to find out the truth. He thought he was chasing a criminal, but in fact he was chasing an answer. Under the neon lights, the identities of hunter and prey are never fixed.
