Kanata, a child at the very bottom of a mercenary group, has been living a life of scavenging for valuable items on the battlefield to survive. His only pleasure is picking up the occasional remnants of magic, known as magic residue, small stones that are essentially useless and eventually disappear. He enjoys looking at these remnants because they are the only beautiful things in his world. However, from these remnants, Kanata gradually discovers fragments and traces of magic. Through persistence and determination, he finally seizes his chance. His rise to power is a result of the accumulation of what was once considered meaningless. Choose your path. Choose wisely.
