I Tried to Usurp Brahma's Throne and Got Bound to a Merit System [Tokyo Revengers]

[I'll start this once my saves reach the threshold for signing a contract. Leaving it here for now.] I'm a cold-blooded, ruthless former assassin, and now just an ordinary employee at Bonten. Okay, I'm not as ordinary as you might imagine. And since I'm aware of my own extraordinary nature, my dream is to replace our current childish leader, who only eats taiyaki and babbles, and become Bonten's new boss. Then one day, I was approached by a Merit System. [Congratulations, Host, you've been bound to the Merit System! As long as you keep doing good deeds, you can make one wish come true!] Me: "..." Why would this System expect a gangster like me to do good deeds? I coldly refused, but it said refusing to bind was not an option. Me: Grab a gun, load it, and rage helplessly at the air. After that... While carrying out a murder, I couldn't help pointing my gun at my teammate. I was about to pursue a car when I saw an old lady crossing the street and got out of the car against my will to help her. While chasing someone down, I passed a jewelry store and threw my knife at a robber in the middle of a heist. Me: "..." That alone would have been bad enough, but my home also started randomly spawning strangers who, according to what I'd heard, had died more than ten years ago. When the first one appeared in my home, a silver-haired, purple-eyed boy who looked a lot like me, my first instinct was to shoot him. The gun was empty. Then, after the System said the other guy had died a long time ago, my second instinct was to shoot him a few more times. I'm afraid of ghosts :) 1. An if story from next door's Truth: the truly cold-blooded, ruthless Black Truth. 2. I feel like writing this, probably over 200,000 words. I'll start once it gets more saves. 3. Harem magnet story.
