Sakura Yae

Yae Sakura used to be the shrine maiden of Yae Village. Despite her devotion, hard work, and wishes for the village's well-being, her ill sister was ultimately sacrificed and used in a barbaric ritual to hopefully quell the houkai. Ironically, the ritual did not work and despite the sister’s last wish, but gradually began to feel hatred towards the village.

The two eventually started a relationship and loved each other, until Sakura got possessed by the will of the Houkai from the purple box and Kallen was forced to seal her loved one away.
