You can try my Novel: Mc is funny, Evil sometimes, not really cold but he is a strategist. I would like to compare him to Lelouch vi Britannia but let's be honest no one can be Lelouch. Every action he takes is a plot even if most can't see it.

Title: Monarch of Darkness, Arsene
Synopsis: Killed by the universe's greatest killer, Truck-Kun. My existence was twisted as I gazed up at King-Yama, staring down at me with revulsion, "You sick bastard, you ate people." He bellowed, glaring at me with disgust.
Snorting, I gathered my courage raising my head high and proud, my voice carrying a hint of pride, "So what, have you ever tried it...Let me ask you, have you ever had sex."
A bewildered expression hung on his rugged appearance as he absentmindedly nodded. A slight smirk crossed my face as I declared, "then have you ate ass,"
"WHAT!!!" He balled in panic, shivering like a guilty man on trial.
"HAHA, you call me disgusting, but it appears you were sucking ass, now that is truly disgusting. I don't judge, but if you ask me, I will stick to cannibalism."
"THAT NOT A FAIR COMPARISON, YOU LITTLE SHIT,"
