Light Novels/Volume 4

"A girl can escape the labyrinth but not her mother!"

"I've finally gotten out of the Great Elroe Labyrinth! Now there's nothing left between me and the surface's all-I-can-eat buffet of fruits, sweets, and water wyrms! The only things that may be problematic are the humans already living here...and Mother, who won't stop following me! Right when I thought I had managed to move out, the absolutely massive spider that is stronger than any dragon just invites herself over without so much as a warning, leaving nothing but craters and rubble wherever she goes! If all my spells, traps, and the dungeon itself can't stop Mother, what can...?"
