HobbyResearch

MottoI know everything!

The genius inventor of Shanhaijing on a day off from her busy life. Contrary to her usual days of being confined to the lab and devoting herself solely to researching new elixirs, Saya is active enough to ride a skateboard and roam around the streets during her days off. However, her constant intellectual curiosity for exploring new things remains the same even when she's taking it easy.
