This time, he will do everything he can to save everyone in the Demon Slayer Corps, find a way to break the curse of the Demon Slayer Mark, and prevent the tragedy from happening again!

"Although it's a transmigration into a book, his personality and consciousness will lean more towards Giyu Tomioka. Or rather, he is Giyu Tomioka, and Giyu Tomioka is also him."

"Of course, this time our Giyu won't be disliked, probably~"

Just as Muzan was about to attack the Kamado family, Hanma Ryoun intervened in time, defeating Muzan in one blow and posing three soul-searching questions.

"What's so interesting about it? What's so funny about it? What do you take your life for?"

Muzan's expression instantly cracked upon hearing this!

He then joined the Demon Slayer Corps and began his journey to slay demons.

Tanjiro: "Brother Hanma, your breathing technique is amazing! What school is it?"

Fan Ma Lingyun: "Huh? What's a breathing technique? I'm all about raw power! There's no mechanics, it's all about numbers!"

Shinobu Kocho: "Why should I be trained by iron fists? It's infuriating, sister!"

Pirates are attacking! Strike immediately to capture or kill them!
