Joou no Rakuin: Horobi no Kuni no Yotogi Miko

Himori Mikoto was born on the small remote island of Himonjima as the heir to a shrine. On this island, it was said that if one enters the forbidden area, they will be cursed by the immortal princess. One day, Mikoto is forced to step into the forbidden forest, and an unprecedented earthquake occurs, resurrecting the curse of the immortal princess... Mikoto, who possesses a special power, will save the world with her own "body." (Source: Natalie, translated)
