Naruto: Hell Demon King

Transmigrate into Hokage, dominate the world, gather a harem of beauties and a crew of powerful underlings, keep Tailed Beasts as pets, and become emperor of the five nations. Use wisdom and courage to roam the world, sincerity and tenderness to win over the women in your harem, and strength and generosity to recruit underlings. Even the strongest can be treated like a pet! Even the five nations will call me king! It's not that I don't want to be weak and rely on the System to get everything! It's that this world simply won't tolerate my weakness! So I'll be ruthless! More ruthless than the whole world! With no outside help, I'll become the strongest in the ninja world through my own power! This world is hell! And I am the devil king of hell!
