Somali and the Forest Spirit Series by Yako Gureishi, 暮石ヤコ

In a world populated by diverse range of tribes, humans have been persecuted nearly to extinction. One day, a forest guardian known as a Golem crosses paths with an abandoned little human girl. This is the story of the bond between a member of the disappearing human species and a guardian of the forest.

Their search for humans leads father and daughter to the village of the witches. Here, they learn of Haraiso's Tale, a book that tells the history of the relationship between two groups: the humans and the others.

Human daughter and "other" father continue their journey to find clues about human beings, who have been persecuted to near-extinction. On their way to the Edgelands, the world beyond the maps, daughter takes a secret adventure into the Below to make her dream of staying by father's side come true. What "others" will they encounter on their voyage across the desert?

Father and daughter continue their journey to the Edgelands in search of humans. A chance encounter with another mixed-species family, an evening of baking in a Woodpeckers' cabin, a reunion in Chompers' Row, the village of tooth and fang specialists... each step of their adventure brings Somari and Golem closer to their goal.

The company make their way to the lawless town of Arishikka, where Shizuku confirms Somari's true identity and questions why a Golem would be traveling with a human in tow. What came next was the story of father and daughter's first encounter...

In search of clues in the outer edges of the land, the four travel to the Cauldron, home of the famous black market auctions. Curios, trinkets, odds and ends -- and a certain book lying among the riches and curiosities on display. Known as Haraiso's Account, the tome was stolen from the witches long ago...
