Zheiro and the Moonlight Sculptor

As a child, Zheiro the sculptor made a promise that he has yet to fulfill. However, poor as he was, it was already hard enough to get far in life as it was, not to mention even being able to complete his promise.

However, thanks to a chance meeting with a certain storyteller, Zheiro now has a chance to fulfill the promise he has made—but not without much effort on his part! Join him as he goes on an adventure in the world of Brave Frontier as he tries to master the legendary sculpting technique known as Moonlight Sculpting.
