Demon Slayer: Reborn as Yoriichi's Younger Brother?

(The story runs from the Sengoku era to the Demon Slayer timeline, and mostly follows the original plot.) Workaholic Lin Ye worked himself to the bone with overtime. On his way home, he “hit the jackpot,” quite literally! A dump truck sent him transmigrating straight into the Sengoku era!

The good news: he landed in a great family, as the third son of the Tsugikuni Clan.

The bad news: his eldest brother was Tsugikuni Michikatsu, who would become Upper Rank One Kokushibo, and his second brother was Yoriichi Tsugikuni, currently the strongest fighter around, but destined for a tragic ending.

Sakuya looked at this family drama on nightmare difficulty and felt doomed. Save his brothers? Change their fate? That was harder than working overtime!

Watching his eldest brother Michikatsu teeter back and forth at the edge of jealousy’s abyss, Sakuya gritted his teeth. Fine, if the usual approach wouldn’t save him, he’d try something unconventional!

If Michikatsu became a demon, then so would he!

As six hundred years rolled by, and Sun Breathing and Moon Breathing were fated to clash once more…

Sakuya, who had been lurking in the shadows of time, finally stepped into the open.

Facing his two brothers, and the entire world of Demon Slayer, he bared the fangs he had hidden for six hundred years:

“Brother Michikatsu, Brother Yoriichi.”

“It’s time to give this tragedy starring the three of us a different ending.”

“I, Tsugikuni Sakuya, may have stopped being human, but I’ll never be a slave to fate!”
