Nirvana Vol. 3 (manga)

After first being welcomed to the world of Gulgraf as a savior goddess, Yachiyo nearly crumbled in the face of the domineering Tenka Landgraf. But with the support of her friends, she finds the strength to answer his deadly challenge–to show she has the strength to carry a whole world’s hope. But surviving that battle is just one step on a long journey, and the next step is the country of Lightning, where never-ending storms power fantastical technology.
