Kiriyu

In the cosmic realm of Aetheris, a war between the goddess Queen Aselia and God King Idon shatters the universe's balance. To restore harmony, Aselia sacrifices her essence, imbuing it into a prophesied elf child, Seira Xilsys, in the human realm of Koralith. Born amidst chaos, Seira's peaceful life is soon turned upside down when forces seek to control her latent divine power. Haunted by loss, Seira embarks on a journey to uncover a reason worth surviving for and discover her true heritage, to harness her abilities and heal a broken world torn between gods and mortals.
