Fan Casting Gravity Soul

When Dipper and Mabel Pines returned to Gravity Falls for their second summer, they expected as much weirdness in the small Oregon town that they're used to, but they never expected to meet people who could turn into weapons and for Bill Cipher to return with a new ally. With help from Maka Albarn and Soul Eater Evans and the other students of the Death Weapon Meister Academy, the Pines family rally to stop Bill and the Kishin Asura from conquering the world.
