Sayonara no Asa ni Yakusoku no Hana wo Kazarou

The people of Iolph have lived quietly weaving daily events into cloth called Hibioru in a remote land.

Their appearances stop growing in their middle teen and they have a lifetime of hundreds of years.

They are called "A Family of Farewell" and have been regarded as a living legend.

Maquia, an Iolph girl who has lost her parents, has spent her calm days surrounded by her friends, but has felt "loneliness" somewhere in her heart.

However, their peaceful life falls apart in a flash.

The Mesarte Army riding on the ancient beast called Lenato invades their town to look for Iolph's blood that offers a long life.

In the despair and chaos, Iolph's most beautiful woman Leilia is taken by Mesarte, and Krim, the boy whom Maquia has secretly fallen in love with, also goes missing.

Maquia is somehow able to escape, but loses her friends and a place to return.

With an empty mind, Maquia wanders in the dark forest.

Then she finds a "lonely baby" who just lost his parents.

The baby is named Ariel, and grows up as a boy.

Meanwhile, Maquia still looks as a girl, no matter how long time passes.
