Come From the Darkness

Li Hai spent enough years as a military commander to see bloodshed that would last several lifetimes, so he does what any burnt-out soldier would do: he quits, moves to the city, and reinvents himself as a detective. Just a normal guy solving normal cases, right? Except the city has other plans. Turns out there's an entire hidden layer to this world, full of people with extraordinary abilities, and Li Hai's past isn't the kind of thing you can just walk away from. The darkness he thought he left behind has a way of finding him, and pretty soon he's dragged back into the kind of fights he swore off. This ONA from Flying Fish Studio leans into that gritty, redemption-arc energy where a guy who's clearly capable of extreme violence is trying really hard not to be that person anymore, but the universe keeps forcing his hand. The fantasy elements blend into the modern urban setting in a way that feels grounded rather than over-the-top, and the adult cast means you're not dealing with high school drama — just a weathered protagonist confronting what he really is. If you liked the tone of The Unparalleled Black & White or the supernatural-meets-street-level vibe of Zhong Hua Xiao Zi, this sits in a similar space. Based on a web novel, so there's likely deeper lore waiting underneath the surface-level action.
