Haru Ayukawa, summoned to prevent a great disaster, is found to have absolutely no magical power. Deemed a failed summoning, she's abandoned and begins working as a cleaner, helped by kind innkeepers. Victor, the summoner, tracks her down, insisting his summoning was successful. Despite their arguments (including Haru's declaration that it was state-sponsored kidnapping), she cares for him after he overworks himself. She's amazed by magic, seeing it as pretty golden stardust, a sight unseen by others. Even without magic, she's unaffected by magical attacks. While repeatedly denying being the saintess, Haru adapts to her new life. Is she the saintess, or a case of mistaken identity? Will the disaster really happen? Despite the chaos, she enjoys her life in the kingdom, her positive attitude influencing those around her. This story follows Haru's growth and journey in a new world, beginning with an unwanted summoning.
