Niki.

On a desolate desert planet, Niki is a "Dhuatara," a human-like child with a lizard-like tail, who lives with her mother in the Sand Sea. Niki is rescued from the off-limits holy grounds by a blue-robed man named Henri from the Mikenai Temple. But then a group of "Dhuatara hunters" appears...? An epic fantasy depicting the growth of a demi-human girl! (Source: Young Animal Zero, translated)
