Merfolk

Merfolk are one of two races living in Wadatsumirie. The Merfolk are the more peaceful of the two races with the women mainly lounging about the realm singing their enchanting song, killing those that become entranced by their singing voices. The men on the otherhand often join the realm's military forces alongside many members of the Hangyojin race.

Appearance
Like the mermaids and mermen of folklore, their upper half of their body is that of a human while the lower half is that of a fish. Unlike the same beings of foklore, merfolk may walk normally on land and even breathe oxygen as though it were normal. Merfolk are based on various different fish, with each member of the species having a different lower body based on their species.

As of now, it seems the mermen can keep more fish-features in the upper body than the mermaids as shown by several members of the Wadatsumirie navy. It is also possible for merfolk to have webbing between their fingers like the Hangyojin, due to interbreeding between the two species. With the merman only, it can also be seen that with older age, the more pronounced their fish-like features become

Powers and Abilities
Weapon Specialists: Merman are born with innate weapons skills. However, these skills are unpolished and can do little more than put on entertaining shows at a young age. As the merman age, their skills are sharpened and refined into more of a specific battle style until they are ready to join the Navy. Upon entrance to the navy, their weapon usage is further trained to the point where they become masters of whatever weapons they were literally born to master.

Hynoptic Voices: The mermaids have incredibly melodic voices, being capable of enchanting those that hear their singing. It is incredibly hard to resist the charms of a mermaid's voice unless you have a strong will or are simply not attracted to females. Once someone has been charmed, the mermaids often bite into their necks, draining them of the blood in their bodies.
