Story
Lloyd grew up never knowing his real parents, living with his sister Trina in the border town of Aslint. He hunts and works as an artificer, while Trina has just begun training as a priestess. Their quiet life shatters when Trina falls mysteriously ill. Lloyd soon learns that Trina carries demon blood, triggered by the presence of a sealed Demon Lord nearby.
To save his sister from a worsening fate, Lloyd must find a way to defeat the Demon Lord—before she transforms into someone unrecognisable.
