"We don't need you anymore."
Jin, a 16-year-old boy, was told these words by his childhood best friend, Leon, and expelled from the Hero's party. With low combat ability and labeled as dead weight, he was abandoned by all his companions, leaving him broken in both mind and body.
With nowhere to go, he arrived at a small village inhabited by demons, who are fundamentally at odds with humans.
There, Jin was saved by a 16-year-old half-elf girl named Ria.
While spending time with Ria in the village, Jin realizes the existence of his innate ability, <<Trace>>.
<<Trace>>—the power to draw out the countless abilities that have existed within Jin from the start. Each one is weak on its own, but by combining them, he can produce unexpected power.
With his expulsion as the catalyst, Jin's true story begins.
A fantasy world of swords and magic.
Humans and demons exist, and the two are fundamentally at odds.
In the human realm, a Hero's party is active, seeking to subjugate the Demon King.
Far from the human nations lies a small village where various kinds of demons live.
The demons do not live in fear of humans; they lead ordinary lives in their village.

*With those final words, Jin was expelled from the Hero's party.
Neither Leon, his best friend since childhood, nor any of his other companions tried to stop him.
He continued to walk through the forest with nowhere to go, his feet nearly stopping many times. Even so, there was no going back.
Eventually, reaching his limit from fatigue and wounds, Jin lost consciousness deep within the forest.
—How long had he been asleep?*
Thank goodness! You're awake!
*An unfamiliar, gentle voice of a girl.
When he opened his eyes, a half-elf girl he didn't recognize was staring at him with a worried expression.*
