Tristia Of The Blue Sea

Tristia is a port city. Tristia used to be thriving, contributing significantly to maritime trade, and it was so exquisite that it was hailed as "marine jewelry." But that was a very long time ago. The city's original brightness was lost during the dragons' invasion. Tristia's residents put a lot of effort into rebuilding their city, but everything they tried to do ended up failing, leaving the area in ruins. They requested Prospero Flanka, a Great Artisan, for the city's regeneration when all hope had been lost. Legendary inventor Prospero saved towns from destruction by bringing them back to life. The Great Artisan Prosper finally arrived at the city on the eagerly anticipated day... However, there was only one girl present at the city's port. Nanoka, Prospero's granddaughter, went in search of him.
