The Nura Clan Chronicles

After Fujiwara Munehide, the Sound Hashira of the Demon Slayer Corps, died in battle, he unexpectedly lost his memory and transmigrated to the Edo period. The current leader of the Nura Clan brought him back to the clan, where he became a swordsmanship instructor to the leader's future heir. But as he kept teaching, why did the heir end up confessing to him? 1. This is an alternate-universe spin-off of the neighboring story, "On the Compatibility of Hashira and Yokai." It borrows only the early setting and characterizations; the plot and other relationships are largely unrelated. 2. Pairing: Rihon. Canon pairing broken. Don't read if that's not your thing. Theme: People should have a sense of responsibility.
