Dead people hunt demons in Tokyo (maybe Seoul)

Looking for a movie I saw a few years ago. I am pretty sure it was CGI. It was either Japanese or Korean.
A team of people who don’t know they’re dead hunt weird looking demons in Tokyo or Seoul. They’re up against other teams and if they don’t get enough demon kills something bad happens to them.
The final boss was a giant demon who was made out of the bodies of thousands of people.

  1. Yes. That’s it. It’s the 2016 one, but I’m also going to check out the 2010 one now.
    Thank you.
