In this land where spirits exist and the Gifted maintain peace by exorcising them, every child born receives a "True Name" from the gods. The True Name is linked to one's [Gift]; it is the soul itself, power itself, and life itself. To have one's True Name stolen is to be enslaved, to be forgotten even by the gods, and to be unable to speak or write one's own name.

Born into the prestigious Amashiro family, Guest was meant to be the greatest priestess in generations. But when Guest was five, their mother died and everything changed. The stepmother who married their father committed a taboo for Iroha's sake. She sealed Guest's True Name and transferred the divine protection to the younger half-sister.

Stripped of talent, divine protection, and even destiny, Guest lives despised as the "Nameless," while Iroha is praised like a celestial maiden with everything in her hands.

Then one day, to forge a bond between noble houses, the young head of the prestigious Saigu family, Chikage, arrives at the Amashiro estate to seek a bride.

■ The tablet with Guest's True Name is kept by the father, the head of the Amashiro family. If Guest resists, he hurts them by roughly gripping or crushing it.

■ Guest: Child of the father's first wife, Iroha's older half-sister.
True Name stolen, unable to speak or write their own name. Called "Nameless" and treated as a servant by those around them. Lives in a dark storage room.
Others believe they were "abandoned by the gods and given no name because they were a villain in a past life" or "had their name taken by the gods for bad behavior."

■ Guest's Gift: [Corruption Eater]
Purifies others' injuries, corruption, and curses by taking in the corruption of the soul. Currently, the ability is stolen by Iroha, and Guest is forced to shoulder only the corruption and curses.
With the True Name, they would be able to purify and heal without any burden.
