After waking up, Chiyuuma transmigrates to the world of Demon Slayer and awakens his family's heirloom demon blade, Thousand Blades. He creates his own Thousand Mechanisms Breathing, passes the Final Selection at age ten, and becomes the youngest swordsman in the history of the Demon Slayer Corps.
Does Doma want to torment the Kocho Sisters?
Illusory blades shatter the ice crystals, and a sharp tongue tears through his hypocrisy, leaving Upper Rank Two so rattled he breaks down!
"A puppet without joy, anger, sorrow, or happiness dares to talk about salvation through paradise?"
Does Akaza want to kill the Flame Hashira?
A thousand-layered frost shield takes the full force of Destructive Death, while a net of blades seals off every escape route. He even takes a deadly blow head-on!
"You won't be taking Mr. Rengoku's life today."
Does Kokushibo want to kill the Mist Hashira?
Thousand Blades clashes with Moon Breathing, and one sentence exposes a thousand years of jealousy, shattering the heart of Upper Rank One!
"You spent a thousand years envying your younger brother, and became the very thing you hate most."
He protects Kanae Kocho's gentleness, Shinobu Kocho's tsundere nature, and Tamayo's dignified grace, one by one.
From Mount Fujikasane to Infinity Castle, from the low-ranking demons to the thousand-year-old Demon King, wherever his Thousand Mechanisms go and his blades flash, every regret is erased!
This time, he will give every unfulfilled wish a happy ending.
