Fuzosheppu

The creature which appears in Chapter 46 parts 1 & 2, often likened to a jellyfish.

Description
Crustacean like head, but mostly formless body. It can fly outside the force field, probably because it is lighter than air. It is a massive creature and has thus far only appeared once. It's transparent, gelatinous body reveals its organs within.

Fuzosheppu is not one monster, but a hive of males that group up and hunt together. One of the males, becomes the "Queen" which is the giant form that we saw it have in Chapter 46. And when the "Queen" dies, the males of the hive go looking for a new one.

Riko guesses that since Fuzosheppu don't hunt in packs and are aggressive, agile, and stubborn, that it is probably very territorial and occupies a vast area. But she was proven later wrong by Wazukyan, when he explained to her                                                                                      that Fuzosheppu is not one creature.

Trivia
