Reborn as the Demon Slayer Corps' Built-In Golden Finger

Not long after the Demon King died, the heroine, a member of the Demon Slayer Corps' Kakushi, was suddenly reborn in a paradise of peach blossoms. There was a house, farmland, and a river, but no people.

To keep from starving, she found seeds and started farming. But before she had even finished turning the soil, the young head of the Ubuyashiki family suddenly appeared in her field. It turned out the paradise was his personal space.

Unable to leave, the heroine told him everything that had happened in her previous life, hoping that this time they could reach a better ending where everyone survived, while she herself simply got on with farming.

But can someone explain why I keep growing crops shaped like people?!

A pink-haired boy and a black-haired girl wearing fox masks: +2

The Flower Hashira, whom she never met in her previous life: +1

The older brother of the Mist Hashira, said to have great talent but who joined the Demon Slayer Corps only when he was near death: +1

The Flame Hashira, who died protecting the train: +1

... ...

The paradise of peach blossoms gradually grows lively and becomes the Demon Slayer Corps' second headquarters.

At night, members of the Demon Slayer Corps who dream of the place come to help the heroine farm, and the information they deliver to the head of the family gets there more safely and quickly.

Even the ordinary crops she harvests have miraculous healing properties. Severed hands and feet can grow back, and the Demon Slayer Corps' death rate plummets.

Then, on the day of the battle in the Infinity Castle, the heroine is finally allowed to leave the paradise. She descends from the sky with a huge supply of medicine and returns to her old job in the Kakushi.
