The first season follows Towa (voiced by Sara Matsumoto) and Setsuna (voiced by Mikako Komatsu), Sesshomaru's twin daughters who get separated in a forest fire. Towa ended up in modern times and is raised by Kagome's little brother, Sota. Ten years later and the sisters reunite, but Setsuna is now a demon slayer with no memories of her sister. They are joined by Inuyasha and Kagome's daughter Moroha (voiced by Azusa Tadokoro) as they set off on an adventure to regian their missing past.
