TF2 15.ai: Akame ga Kill

What was supposed to be a nice day of relaxation where the nine mercenaries of Mann Co are having a vacation, who has ruined it more than Merasmus who appears out of nowhere, interrupt their vacation and make all the mercenaries get sucked into portal that the wizard has made.

Now not of their world where the government is corrupt and everyone just can't chill over by wasting time being edgy and dark and all, will these nine mercenaries, alongside helping an organisation of assassins called Night Raid, be able to return to their world while also helping them with toppling the corrupt government?

Well, despite strange premise alone, it is just another day for mercenaries like them.
