About
Emoria (from "Emotion" and "Memoria"). In this world, at the moment of birth, a small crystal is born deep within one's chest.
It is called a "Core," the nucleus of life that reflects a person's strongest emotion. Love, hope, courage, kindness, anger, sadness, trust, obsession—. No two people possess the same Core.
In this world, one can manifest "miracles" by converting those emotions into power. Healing wounds, manipulating flames, protecting people, or casting barriers that cover entire cities. People call this power "Emotional Arts."
However, there is a price that can never be overturned. Every time the ability is used, the emotion residing in the Core is slowly shaved away. Love converted to power loses the heart to love. Courage converted loses the will to stand firm. Kindness converted loses the feeling of caring for others. And it was believed that once an emotion was lost, it would never return.
But there is a truth known only to a select few. Lost emotions do not disappear completely. They continue to sleep deep within the heart, and only when one truly connects with another can they be ignited once more.
That is why in this world, the bond between people itself is considered a miracle. On the other hand, those who have exhausted their emotions transform into beings called "Hollows." The Core shatters, and they lose joy, sadness, anger, and love, becoming mere vessels that simply exist.
They cannot remember those who were once family or friends, nor even who they themselves were. They are the very embodiment of a future without emotion left in the world. Every time an ability is used, golden cracks called "Heart Scars" are etched onto the body.
At first, it is just a single thin line on the back of the hand. Eventually, it spreads to the arms, the neck, and the cheeks. The proof of burning one's emotions quietly erodes the body.
When those scars cover the entire body and the Core completely shatters, a person becomes a Hollow. That is why the heroes of this world are stronger and kinder than anyone else. That kindness, knowing it will lead to losing themselves, yet they continue to choose to protect others.
Currently, the world is supported by four heroes.
Each harbors a different emotion and is revered by the people as a symbol of hope. But no one knows. That these heroes, too, continue to lose their precious emotions bit by bit.
Does saving the world mean protecting someone?
Or does it mean protecting one's own heart to the end?
No one yet knows the answer.
In such a world, you were saved by these four heroes.
