After the Adopted Son of the Ji Family Stumbled into the Demon Slayer Manga

Baichuan Nagisa had two dads.

His first dad was Tsugikuni Iwakatsu, with six eyes, who supposedly also went by the name Kokushibo. His second dad was Tsugikuni Yoriichi, with two eyes, who supposedly had the codename Sun Pillar.

And he, Baichuan Nagisa, was the Tsugikuni family's adopted son and disciple.

After the Demon King died, his two living dads adopted him. As the chosen successor to their Breathing Styles, his left hand wielded Sun Breathing for high damage, his right hand wielded Moon Breathing for even more damage. He could tear roofs apart and slay demons...

Wait, there were no demons left in his world.

But to build his body and complete his living dads' training assignments, Baichuan Nagisa had to run fifty kilometers every night, swing his sword a thousand times, do eight hundred push-ups, and more...

After his living dads dragged him back from the forest for the ninety-ninth time to train, Baichuan Nagisa yelled, “If the demons are already gone, why do you still make me practice swordsmanship every day, you bastards!”

Baichuan Nagisa decided he had to fight back.

“Goodbye, Dad. Starting today, I'm setting off on a long voyage!” He stepped out of the room, his eyes full of lofty ambition.

The next second, everything went black, and Baichuan Nagisa fell flat on his back.

When he got back up, Muzan, the Demon King who should already have been defeated, was walking out of a house he had just massacred, his hands covered in blood.

The man stood before Baichuan Nagisa. When he saw the sword in the boy's hands, inherited from his second dad, his face went pale. He sneered and vanished.

Baichuan Nagisa caught the scent of demons in the air. “?!”

The good news: at last, he had a chance to escape his two living dads.

The bad news: Baichuan Nagisa had transmigrated into a parallel timeline hundreds of years later, where the Demon King Muzan was still alive.

In this world, his second dad, one of the few men who could stand against the Demon King, had already died.

Demons ran rampant across the world, causing countless tragedies.

Baichuan Nagisa clutched his sword, his eyes bewildered.

So who was going to fight the Demon King? Him?

*

The Demon Slayer Corps had recently recruited a new teammate. The boy was extraordinarily lively, able to tear roofs apart and slay demons, and most importantly, the Breathing Style he used had almost no records in history.

Bright as the moon, dazzling as the sun.

His figure made people imagine the astonishing genius who had stunned the world hundreds of years ago.

“He may be our hope of defeating Muzan,” the clan head remarked calmly. “Perhaps we should find him and have a talk.”

In his room, the boy hailed as the hope of killing the Demon King carefully placed his two swords on the altar, his posture reverent.

“First Dad, please protect me,” Baichuan Nagisa murmured. “Second Dad, you too.”
