Infinite Dendrogram: SP Omnibus (Light Novel)

 Corpse Stronghold, Abyss Shellder: this elusive and deadly monster shook the world with its ravenous hunger, consuming any who dared enter its domain. Ignoring all those who advised her it was a fool’s errand, Riella―the young commander of Granvaloa’s adventure fleet―sets off on a voyage to hunt the creature down. With few allies at hand, a posse on her tail, and her quarry a beast of unimaginable strength, her chances do indeed look slim...but Infinite Dendrogram is not a world of absolutes. Knowledge is power, and so too is sheer, overwhelming strength. With enough of both, even the most fearsome of creatures may just face their demise.
