Ruling the Heavens with Haki and the Sharingan

Multiple heroines. The protagonist is like Homelander: he doesn't eat beef and does whatever he wants. He never takes a loss, and he collects all the beauties across the Myriad Worlds.

The protagonist is just an ordinary person who suddenly gains power, so it magnifies his inner desires. He has a little kindness in him, and there's nothing wrong with his sense of duty.

Armed with the three types of Haki from One Piece, the perfect Sharingan from Naruto, and the martial arts and appearance of the older Seven from Killer Seven, he wields the Thousand Demon Daggers as he travels through the worlds. His first worlds include The Smiling, Proud Wanderer, The Legend of Qin, The Return of the Condor Heroes, Demi-Gods and Semi-Devils, Uncle Nine's world, The Outcast, A Chinese Ghost Story, My Date with a Vampire, One Piece, Hokage, Jackie Chan Adventures, Ultraman, Lotus Lantern, Transformers, and the Qin, Han, Three Kingdoms, Jin, Tang, Song, Yuan, Ming, and Qing eras, as well as Hong Kong crossover stories. The System's Immortal Realm is mainly for recruiting heroines and giving them a place to stay and something to do. Feel free to skip it if that's not your thing.
