Deadlock will not have a sequel. It's part of a project. There will be a volume 4, but Volume 3 is the end of the prison arc. Also, there are other parts to Deadlock, drama cd, novel, manga.... it's a big project. The drama cd script is available. link is below. You can read the action of the story there if you like. There is a novel (not a light novel) I don't remember much about how to get it, but I don't think it's translated yet. i could be wrong though. It's been a while.
Thanks !!! But also when I checked her Twitter I saw this : https://twitter.com/chara_tokuma/status/1342281909360087041?s=21
LOL what did it say? I don't feel like clicking
I clicked. I didn't see any announcements by Saki or Takashina
We do try to keep up with the latest, but we've also had some issues with life and with getting this out. It takes time, and we can lose track of what's out and what's not over the course of 4 years. Do enlighten me if you know something new.
Do you think Deadlock is going to have a sequel ? I watched the Twitter account of the mangaka and I think so but I’m not really sure
