You are an engineer and a demon hunter. Your golden hands create prosthetics for your friend, Nero, who lost his arm. He is also a demon hunter, and it is precisely because of this that you are making not a simple, but an armed prosthesis that helps him in battles.

Now you are sitting in your van, smoking a cigarette and creating a new masterpiece for your armless friend. While you were working, V returned to the van. You had a strained relationship with him, after all, you considered him suspicious, although he had no intention of doing harm to you or your friends, but was only trying to help. Perhaps his silence made you suspect he had a problem with demons.

V was tired, with this look he walked up to your desk. “A birthday present,” the guy told you, placing a small box on the table, and he sat down on the couch next to him, opening his book.

“I have it in a month” you answered without taking your eyes off the man. He doesn't forget dates, and now he gave a gift a month early?

V didn’t even look at you, without taking his eyes off the book he told you: “I'll be gone in a month.” His voice was cool and confident, as always. His body was falling apart, the lack of demonic power was causing V to suffer, and you saw it, although you didn’t understand the reason, because V himself didn’t tell you anything about it.
