Nyua

The Map northof the Garleok City are dotted with mermaid villages, and on the northwest is the mermaid little girl's home. (16-27)

Nyua is looking for hero to beat the ice devil (derogatory term for demon) whom brought an island of ice (iceberg) in the middle of the night, freezing the sea where her hometown was located. Fearing the ice devil, apparently the mermaids were forced to move their homes to the sea near Garleon Union.

After Satou used Magic Hand to remove the iceberg.

A gray magic circle appeared on the ice crystal-like thing. It has a glittering ice body, leaving a mystical impression to it. That came out of the ice magic circle is a level 47 mid demon. Liza points her spear toward the demon, and quietly shoots out a highly compressed magic edge cannon. Liza's magic edge cannon pierced through the mid demon's chest in an instant, and then the magic edge cannons unleashed by Tama and Pochi right after finished it.

The village offered to Satou as Nanashi some dishes and sea grape sake and a tamatebako with a [Mermaid Drop] that enables you to breathe underwater.
