Senna is a beastwoman and a former resident of Howling Village. She appears to be a very nervous but kind young woman, although she can be assertive at times.

Born and raised in the mountain settlement known as Howling Village, Senna is the daughter of the village chief, and while still living in her native land she used to mine ores and manufacture various goods that would serve as trade materials that would be exchanged for food, which was difficult to grow in the mountainous area.
