Guardian Cat Girl Hiju

Tianga Yuuto (voiced by Daisuke Hirakawa) is an introverted boy who lives alone and lonely. Regarding life, Yuuto just hopes to spend the rest of his life in peace. But things went against his wishes. On the day of his 16th birthday, a black-haired girl named Noihara Himari (voiced by Ami Koshimizu) appeared in front of him. At the same time, there were also terrifying monsters attacking Yuuto. After the battle, Hiju told Yuto, who was still in shock, that he was a descendant of the "Twelve Families of Demon Slayers". In the past, in a world where humans and monsters lived together, Demon Slayer played a solid role as the guardian of mankind. But as time goes by, their abilities gradually weaken, and eventually most of the Demon Slayers end up living in the human world and become ordinary people. Nowadays, the power of monsters seems to be making a comeback. To this end, Yuuto must muster the courage to fight hard to protect the people he loves from harm.
