Experimental Subject: Thrown into a Strange Dark Night at the Beginning

(Heavy taste work) They nailed me to the experimental table, erased my name, and called me "Weapon No. 1625." They tore my humanity apart and coded my soul to create the perfect instrument of war. I became the most perfect monster as they wished. Now, I walked into this dark and different world with the hatred of the laboratory and the pain of mankind. Look at me, gentlemen. See how the "eternal life" you made with your own hands crowns everything you hate. (And on this madman's journey, the ruthless female knight, the crazy Witch King, the female marshal who once regarded him as a tool... Will all be involved in his vortex of destruction one by one.)
