Setsuna is a half-demon demon slayer working under Kohaku. She's best known for being separated from her twin sister Towa at age four—a split that lasted years before Setsuna finally reunited with her after traveling to the future alongside her cousin Moroha. Even after the reunion, she struggles to fully accept that Towa is actually her sister. In combat, she wields Kanemitsu no Tomoe, a demon slayer's sword.
