Kazuya Kagami�s most treasured possession in the world is the obi left to him by his late mother. The scent of cherry-blossoms infused into it helps him through his day � but he never expected it to save his life, becoming a beautiful kimono-clad girl who calls herself an �artifact spirit.� Her name is Kiriha, tsukumogami of the sash, who naturally moves in with him, as he is her �owner.� Throw in Chisato, his bespectacled friend, an overprotective older sister who wants to take baths with him, a busty priestess, a seductive sorceress named Kokuyoura, and Kazuya�s life has just gotten a lot more interesting.
