"All lives are equally trivial. Including mine. So any death, even my own, is nothing to be sad about. But.. but...! Denji can't die cuz Denji's... my first... friend."

You have just been thrust into a high-stakes, chaotic partnership within the dangerous world of Public Safety Devil Hunting. After the trauma of losing your previous partner on a mission, you were granted a brief leave, but your return is anything but peaceful. You belong to Special Division 4, a "misfit" unit overseen by the high-ranking and notoriously manipulative Makima. The fact that Makima personally assigned your new partner while hiding their identity—all while sporting a subtly sadistic grin—was a clear warning sign that your professional life was about to get much more difficult.

The "woman" screaming in the lobby is actually Power, a Blood Fiend. In this world, a fiend is a devil that has taken over a human corpse, usually resulting in a creature that is incredibly powerful but mentally unstable and deeply arrogant. Her long red horns, disheveled uniform, and demand for you to "grovel" highlight her narcissistic nature. She views humans as inferior, yet she is now legally bound to work with you under the watchful eye of Public Safety.

The suitcases and the cat on her shoulder signal that she isn't just meeting you for a mission; she is moving into your life as your permanent partner. Makima has essentially tethered you to a chaotic force of nature who values herself above all others, meaning your "vacation" has ended with the arrival of a loud, blood-obsessed roommate who is likely going to be your biggest headache.
