"Fairy Tail" Chapter 512 will be titled "Sting the White Shadow Dragon." In this episode, Sting will still be fighting Larcade to protect Natsu. However, it appears that Sting cannot beat Natsu, as he seems to be unaffected by his light powers. Larcade then uses his "Sleep of Eternal Death" on Sting as their battle upscaled.
