Oh hi there, I see you have stumbled upon this one shot! This is something I did for fun and being in the fandom I haven't seen much NK Cell and Killer T Cell works (or it's because my searching skill aren't great and all but I do know they do have fan works separately) This is set in a Human AU where Killer T is a SWAT member and NK is a Lieutenant who is also a soon to be secret agent. Enjoy!
