Mermaids (Delicious in Dungeon)

Mermaids are a type of demi-human from the manga Delicious in Dungeon. They appear in Chapter 15.

Biography
Mermaids will sing in an attempt to get adventurers to defenselessly wander over to them. They will not attack directly, though it is said that they will drag their victims into the depths of the ocean if successfully enchanted. Their mesmerizing song can be stopped by blocking one's hearing, although it leaves one vulnerable to other methods of attack. A better method is to sing along with the mermaids' song, which will startle them into leaving.
