Sea Ghost

One of Deep Sea Demons types, they comes in many variants that can be easily identified by their fish-like appearance and their occasional attack of fisherman. They are often called by crows of the sea, due to emitting a noise similar to these birds.

## Appearance

All of them seem to be alike marine animals like fishes, crabs and squids. Also some of them fave human hands.

## Background

Initially seen by the Fjords as monsters disguised as fish who bite and drag fisherman into the water, Thunder believes them to be simply Demonic Beasts. After the underground exploration of the Great Snow Mountain, they were eventually associated to a new sentient civilization, the Deep Sea Demons. After learning of the origin of the Demonic Beasts and Demonic Hybrids, they can either be considered as a water based variant of them or as another species altogether. Nevertheless, they are known to the demons as the lowest constructs of the Sky-sea Realm, with their only advantage being their numbers. Due to this, they are most suitable for filling the battlefield.

## Chronology

The term was first mentioned by a sailor after seeing a fish-like monster, while Tilly Wimbledon explored the previously Shadow Isles of the Fjords along with Thunder.  They are then seen by Tilly when she travelled to Border Town via Shallow Beach for the first time, eventually killing a bunch of them with the help of Shavi, Andrea and Ashes.  Though they were known for a long time by humans who traveled the Ocean like the Fjords people, it only started to be associated to a sentient civilization after the underground mountain exploration.

Joan was initially believed to be a Sea Ghost by sailors due to her scales covering her cheeks, neck, arms and legs.  Thunder recounts to Roland the death of a friend who got killed during a Sea Ghost attack, during Lightning's awakening.  During Thunder's exploration of the Ocean further away from the continent than the Sealine, they were attacked by Sea Ghosts  and other Deep Sea Demons after apparently arriving close to the Sky-Sea Realm territory. After sometime fleeing, Devour appears to have intervened and attacked them to evolve himself. After being stranded from Thunder's exploration while still in the Fjords, Joan encountered several Sea Ghosts and other Deep Sea Demons and though attacked by them, managed to escape.

When entering the Bottomless Land after the Demon Civilization and Human Civilization's truce, countless sea ghosts propped up their heads over the sea as they cawed at the floating island. It was as though dense black pores had bloomed on the sea surface. Just sweeping across it with one's eyes left one's scalp tingling. The bodies which were floating beneath the water made the seawater appear a strange black color.

After the Custodian agreed to stop the Battle of Divine Will and step down from his position, a great magic ripple escaped from the Bottomless Land and made every Blade Beast and Nest Mother collapse to the ground, leaving only the Sea Ghosts unscathed. After it, free from the Custodian's control they receded like the tide.

## Abilities

Sea ghosts have different abilities due to their different evolutions, and they usually use their crab legs, humanoid arms, and large mouths with shaped teeth.

They often disguise themselves as fish and take the angler’s bite and drag them back into the water. Also they usually attack in swarms, but some of them attack alone.

## Known variants

* **Frist Sea Ghosts**: A fish with a crab's short feet.
* **Second Sea Ghosts**: A fish-bodied with crab-legged.

## Trivia

* No ships seem to be able to outstrip a sea ghost.
* One of the Thunder’s crew members has heard a rumor that after eating a man does a sea ghost start to growing human hands.
* The creation of this Deep Sea Demons' type might have some real world inspiration since it harks back to sea monsters often mentioned in literature like Kraken, Hydra and Loch Ness Monster.
* Along with the Demonic Beasts and some of the Demonic Hybrids, the Sea Ghosts are one of the few species of the Deep Sea Demons still alive after the end of Battle of Divine Will.
