Demon Slayer: Tanjiro Always Hears My Last Words

【Demon Slayer fanfiction + Two male leads + Slow-burn healing + Making up for past regrets + Ensemble cast + Happy ending】 Mochizuki Kawa transmigrated into the world of Demon Slayer three years ago and gained the ability to hear the last words of the dead. As long as he fulfills a dead person's final wish, he can borrow the power they left behind. With this ability, he saves people who were supposed to die and changes one tragedy after another, trying to win everyone a regret-free dawn. But he soon discovers that every time he changes an important death, he loses one of his most precious memories. At first, he only forgets the taste of a dish. Later, he forgets why he ever picked up a sword, forgets the people he once saved, and even forgets the red-haired boy who always ran after him, refusing to let him face death alone. While everyone celebrates the future they've changed, only Tanjiro can smell Mochizuki Kawa slowly fading away. So he writes everything the two of them have been through in a notebook, and tells the person gradually forgetting himself, over and over: “It's okay.” “Every time you forget me, I'll get to know you all over again.” In the end, everyone remembers how dawn came. But no one remembers that a boy named Mochizuki Kawa gave up the reason he most wanted to live for the sake of that dawn. Except Tanjiro. Because this time, he won't let Mochizuki Kawa face his ending alone.
