Demon Slayer: Invincible from the Start with Mist Breathing

Hei Shi transmigrates into the world of Demon Slayer, where he encounters a female Muzan. She takes a liking to him and turns him into a demon.

Since he refuses to feed on humans, he becomes incredibly weak and is taken to Mount Fujikasane, where he joins the ranks of countless lesser demons.

Unexpectedly, he runs into the two Butterfly sisters, who are taking part in the Final Selection.

Faced with Kanae's blood, he overcomes his demonic instincts and successfully activates the Strongest Demon King System.

He can grow stronger by feeding on wisteria flowers, and even transform his blood?

And so, a demon is born who smokes Wisteria cigarettes, carries a Tang-style saber, and uses the Breath of Smoke!

Kanae: "Mr. Heishi, the latest batch of Wisteria cigarettes is ready! Please give them a try!"

Tamayo: "Mr. Heishi... I can hardly wait to see what happens when you eat the Blue Spider Lily!"

Daki: "Lord Heishi, I've learned a new dance. Would you like to see it?"

Atop Mount Fujikasane, Heishi gazed calmly at his entire squad of beautiful subordinates.

"This... is the script I, Kyuzan Heishi, wrote!!!"
