Ami lives in the village of Toltus along with her brother, Chester. They live alone together, as their parents were killed while they were little. One day, Chester and his friend, Cress Albane, go hunting in South Forest. Ami gives Cress a stuffed doll version of him as a present, and Chester gives her an apple that the item shop owner gives him. Unfortunately, as Cress and Chester hunt, Mars Uldole and his troops attack the village, looking for the pendant that seals Dhaos, and Ami is killed along with the rest of the villages. Broken by the death of his last family member, Chester remains behind to bury the villagers as Cress flees to Euclid. Chester later reveals regret to Arche Klein for not having been able to avenge her, as Mars is killed by Dhaos before either Cress or Chester have any chance to confront him. Ami's death is Chester's primary motivation that spurs him on his quest and causes him to desperately hate Dhaos.
