Demon Slayer: They Call Me Murata, but I’m Strong Enough to Protect the Hashira

[Demon Slayer parallel world] + [Murata with a bodybuilder's physique] + [Reincarnated with a Demon Slayer Mark] + [Slow-burn early cultivation with steadily increasing stats] + [Single heroine: Kanae Kocho] + [Original Sea Breathing Style] + [Story begins eight years before the main plot]

Zhao Dezhu, a PE student, unexpectedly reincarnates in a parallel world of Demon Slayer and discovers that he has become Murata, the Pillar of Covering.

His parents are still alive, and he is still very young.

Determined to change the story, he begins training like crazy.

Five years of training, eight years of real combat!

Who could have guessed that the Pillar of Covering, whose push-ups looked like a butterfly flapping its wings, would actually manage to protect everyone?

Giyu Tomioka: “Thank you, Murata, for saving Sabito. Without you, I wouldn't be who I am today.”

Shinobu Kocho: “Big sister, when are you marrying Murata?”

Mitsuri Kanroji: “Mr. Pillar of Covering! Please come to my wedding with Mr. Iguro!”

Kyojuro Rengoku: “Akaza, when you're reborn as a human in your next life, let's have another match! Ha ha!”

The day of the decisive battle at the Infinity Castle...

Muzan Kibutsuji: “Wait, what? What kind of Pillar is the Pillar of Covering? And what the heck is Sea Breathing?”
