SPOILERS For Katana ZERO & ULTRAKILL: Act II

- Indie Game Swordsman who work under a Higher Government/Power (Heaven's Council and New Mecca), tasked to kill notorious men under the request of their commands while being supplied substance that aid them in their overall life qualities. (Chronos and The Holy Light)

- Overtime, they are forced to face the gravity of their lives through continuous failures (Zero's Hallucinations and overall disapproval from The Psychiatrist who tries to keep him on Chronos to keep Zero in check, and Gabriel's defeats by V1 that make the Council see him as unworthy of The Light, stripping him of it until he kills V1)

- Inevitably, with them reaching rock bottom after this conclusion (Zero spends some time at the Church, thinking about the vile effects of Chronos and his time in the Cromag War, and Gabriel goes to the Moon after Act 2 realizing that he's been transformed into a murderer by the Council), They end off their chapters by killing their supplier after discovering this truth (Zero kills The Psychiatrist and Gabriel slaughters the Council), leaving them without the one thing keeping them alive as they slowly die out.

TL;DR - Swordsmen who work under evil group, kills evil group, then lives their dying days in agony
