Setsuna

is the deuteragonist in the anime series Hanyō no Yashahime.

History
Setsuna is a half-demon demon slayer who works under Kohaku. She was separated from her older twin sister Towa when they were both 4 years old but was reunited with her after traveling to the future with her cousin Moroha.

It appears Setsuna at some point suffered from some sort of sleep-related childhood amnesia.

Trivia

 * Setsuna is the only known demon slayer who is not a full human.
 * Unlike most of the others hanyō, including her paternal uncle Inuyasha, Setsuna had no visible physical indication of being a half demon, such as dog ears. However, she has a mokomoko that crawls from her right shoulder and splits in two in the middle of her back.
 * Despite being an Inu-hanyō like her uncle Inuyasha, she and Towa seem to age at the same rate as humans.
 * Setsuna's name, like her sister Towa's, is homophone with a time word, "moment" or "an instant". This is probably an allusion to the fact that both sisters travel through time.
