Shangrila: The Pilgrimate to the Broken Past

The land of Shangrila, a land adjoining the human world, is famous for its peace and prosperity. In this world, the humans and the ashuras have lived in peace and have also experienced great wars. The only hope for Shangrila's survival is the "power of Srikandi" that mysteriously permeates Ayu, a high school student living in Indonesia. Ayu, who is then targeted by the Ashura, must quickly master the power of Srikandi, before Shangrila disappears forever. (Source: Goodreads, translated)
