The story is locked while I work on the draft. I'll post it once it's finished or at least halfway done. If you're interested, please bookmark it!
After being killed in a siege by the Demon Slayer Corps, Upper Rank One should have gone to hell, but instead he was reborn. He returned to the age of seven, before anything had begun. He was once again Tsugikuni's carefree eldest son.
But soon,
he realized that something seemed off about this second run through life?!
Part 1.
"Brother, do you want to become the world's greatest swordsman?"
Once again, words powerful enough to ruin Iwakatsu's whole life drifted lightly into his ears. The speaker continued, completely unaware of the damage he was doing:
"Then Yoriichi will become..."
"The world's second-greatest philosopher!"
Iwakatsu: ?
Iwakatsu: Wait... what did you say you were going to become???
Part 2.
His twenty-fifth birthday was drawing near, and there wasn't much time left to chase the sun.
On another moonlit night with no way out, the progenitor of demons smiled and held out a hand, offering the lost swordsman a way forward.
"Become a demon, and then..."
"You can be my secretary! No days off, twenty-four hours a day. Then you won't have time to think about the meaning of life. Have you finished the reports I assigned you? Did you get the invitation from the Ubuyashiki family? And I want pork cutlet rice for dinner. There was no takeout in the Warring States period, so go get two portions and we'll eat together."
Iwakatsu: Lord Muzan, are you not even pretending anymore?
Part 3.
Hello, I'm Muichiro.
I was in the Infinity Castle, just finished praying for my ancestors to protect me, when one appeared right across from me. And he looks exactly like the instructor who trained my brother and me.
But the bigger problem is...
After ten years of working hard to learn swordsmanship, I arrived at the Infinity Castle only to discover that the decisive battle against the Twelve Kizuki consists of music, chess, calligraphy, painting, eight languages, and a best-of-three debate tournament.
Watching the master and the Demon King furiously argue over their respective principles, Muichiro tilted his head without expression.
Can this really still be called a hot-blooded shonen manga?
Reader's guide:
1. This story has both Tsugikuni brothers reborn, so the butterfly effect is everywhere.
2. The brothers will have intense conflicts, and there will be angsty parts, but don't say the two of them aren't suited to be brothers! Don't underestimate the bond between our sun-and-moon twins!
3. A fantastical premise links the original story with the Academy Arc. The bonus chapters will feature the younger brother as an antique shop clerk and the older brother as a senator's secretary. It's fine if you haven't read those stories; you can treat this as a modern alternate universe. Anyway, there are tons of original settings in this story ( )
Theme: Learning to communicate can make the world a better place.
