Ura Sekai Picnic

Moments from death, Sorawo is saved by the mysterious Toriko in the Otherside. Attracted to its beauty, she soon discovers that this dimension is inhabited by monsters once thought imaginary. Joining with Toriko in her search for a missing friend, they set out to explore this nightmare-realm and maybe make a little money. What they encounter could bring enlightenment—or drive them mad!
