Ethel is the commander of the Colony 4, a Kevesi Colony. She wields a pair of slender swords. She is famous for defeating three enemy colonies at once with only 100 soldiers at her command. She is called Silvercoat Ethel by all the forces of Keves. In the past, Ethel saved Noah and his friends from an Agnian attack. In battle, she wields Dual Rapiers and is of the Flash Fencer class. Ethel is temporarily recruited as a Hero after completing the Hero Quest No Want of Courage, but cannot be used after the party leaves Colony 4.

For Ethel to rejoin the party, a member of the party must reach rank 10 with the Flash Fencer and Seraph classes. The party then must go inside the lab at Colony Omega with Cammuravi in the party. By having Ethel undergo the maturation process, she will be able to rejoin the party at rank 20.
