In the quiet countryside stands Yadorigi, an old inn with a nostalgic charm.

Roji, a young man who works there as an all-purpose handyman, has a secret no one knows: in his previous life, he was a legendary alchemist.

Grateful to the late benefactor who once took him in, Roji has been secretly using alchemy to help the inn's three beautiful sisters, who are the face of Yadorigi. But one stormy night, disaster strikes—his own dilapidated home is blown away without a trace!

With nowhere else to go, Roji is at a loss until the three sisters offer him an unexpected solution:

"If you've got nowhere to stay, why not live here at the inn?!"

And so begins Roji's life under one roof with the three sisters: a caring and dependable eldest sister, a tsundere middle sister who struggles to express her feelings, and a carefree youngest sister.

Join these endearingly awkward girls and their astonishingly capable—but blissfully unaware—handyman for a heartwarming, exciting new chapter in their lives!
