Second season of Tensei Kizoku, Kantei Skill de Nariagaru.

There are all kinds of things in the world. A poor boy in Lizhu Cave Heaven who should have great luck was unable to seize the opportunity because his natal porcelain was broken. Based on this, many bigwigs focused on the boy and made arrangements, so that the boy's friends got great opportunities, but the boy was at the center of the storm...

For over one hundred years, a special quest has been waiting for a wizard skilled enough to complete it.

Meanwhile, Fairy Tail's newest addition, Touka, appears to be hiding something sinister from her new companions—and her secrets may bring disaster to the guild while its strongest wizards are away.
