Demon Slayer: Master of Both Medicine and Martial Arts

Hello, I'm Jiang Jiu, a traditional Chinese medicine doctor. I survived the college entrance exams and made it through that tragic love story between Blue and Green, but no matter how carefully I planned, I couldn't outlast the pandemic. Heaven must have taken pity on me, knowing I died young before my time, and gave me a chance to start over. But... why am I still stuck in an unfinished Demon Slayer world, in a foreign land? Damn it! Since I'm here, I might as well revive the traditions of our medical profession. Treating the sick and saving lives is a given. If I can even save people from their untimely deaths, I may as well go all the way. Learning martial arts and mastering the sword shouldn't be too much to ask, right? And since I'm already learning swordsmanship, I can't let a transmigrator down, can I? Why not go chop up that piece of trash, Muzan? “This child was born in March, so let's call her Yayoi. May she bring the Demon Slayer Corps hope for new life, just like spring's new beginnings.” “Brother Kagaya, a person like you deserves to live to a hundred and enjoy the blessings of a peaceful age!” “Master, teach me the sword. I swear to wield it to right wrongs and protect those behind me.” “I dreamed of a peaceful age. I was born in my master's hometown, a place of beautiful mountains and clear waters. Before I knew it, I'd put down roots there.” [Female lead transmigrates into another person's body + original side pairing + Obanai and Mitsuri stay together] [Female lead's love interest is Kyojuro. She believes love and bread deserve equal shares.]
