Mati was a typical blacksmith's apprentice, until the fateful day he discovered a long-lost demon sword hidden in a cave near his village.

To make matters more complicated, inside the sword is the trapped soul of a girl named Lyra from hundreds of years ago.

Despite having never left his valley and barely able to lift the smith's hammer, Mati vows to help gather the eight crystals needed to free Lyra.

Now, many years later, the duo are near the end of their journey, and Mati has rather inconveniently fallen in love with the disembodied voice of the girl he has never met.

But with the fateful day approaching, will Mati be able to muster up the courage to not only secure the last crystal, but also confess his true feelings to Lyra?
