Demon Slayer: I Became Yoriichi Type Zero, and Muzan Carried the Cart Away

[Just Started Getting Ratings, They’ll Go Up Later]

[System + Mechanical Ascension + Overwhelming Power + Everyone Survives + Modern Firearms Exorcise Demons]

He transmigrates into the world of Demon Slayer, but doesn’t become a Breathing Style swordsman or a demon.

Lu Li discovers that he has transmigrated into the legendary mechanical puppet from Swordsmith Village: Yoriichi Type Zero!

A hellish difficulty setting from the start? His whole body is rusted, and he can’t move?

[Ding! Divine Mechanism System activated!]

[Consume Tamahagane: body durability +1000%!]

[Consume Nichirin Blade fragments: unlock thermal serrated blade!]

[Consume Blood Demon Art: install anti-gravity thrusters!]

And then the whole story takes a turn.

While the other Hashira are still training their Breathing Styles, Lu Li has already fitted himself with six mechanical arms and six black-and-gold Gatling Nichirin Blades.

While the demons are still showing off their regenerative abilities, Lu Li silently pulls out his 800 mm “Nichirin Energy Cannon.”

[Scene One]

On a snowy night, Muzan arrives at the Kamado home.

Lu Li, spreading all six arms as steam billows from his body: “Take your filthy hands off my family.”

Muzan, spotting the earrings: “Yoriichi Tsugikuni?! You came back from the dead?! No... what the hell, is that a giant robot?!”

[Scene Two]

On the streets of Asakusa, Muzan blends into the crowd.

Lu Li: “Breathing Style? Too slow. Try my ‘long-range Nichirin sniper shot’!”

BOOM!

Clutching his severed arm, Muzan runs back to the Infinity Castle in tears. “Nakime! Close the gates! That hunk of metal is back again!”
