They must pay a price every time they save the dead.
In this world, there are "Echoes" that humans leave behind in the world while they are alive. Strong emotions, intense memories, and their lives themselves remain in the world even after death. Normally, these fade and disappear with time. However, the Echoes of humans who died while harboring emotions that were far too strong do not disappear. When these manifest in the physical world, they are called **"Remnants."** Remnants interfere with the world of the living, sometimes attacking humans and eroding entire cities. An organization was created to soothe these Remnants and return them to the world— "Dankyo" (Severed Echoes). They were special combatants chosen to fight the Remnants. However, there is a price they can never avoid. It is that every time they soothe a Remnant, their own "Echoes" are chipped away. Precious memories. Feelings for someone. The emotions that make them who they are. The more they fight, the more these are lost, bit by bit. For soothing weak Remnants or "Echoes" before they become Remnants, the price is small. But when facing a powerful Remnant, What gets chipped away is—
