The New Girl's Contractor Season 1

Tojo Basara (voiced by Nakamura Yuichi) is an ordinary high school boy who has always lived a life of dependence on his father. One day, his father suddenly talked to him about his sister. This move by his father, who had always been unconventional, made Basara feel very nervous. Sure enough, his father announced the news of his remarriage and brought back two lovely girls, who are now Basara's sisters. Mio Naruse (voiced by Ayaka Asai), who has a devilish figure, a proud and aggressive personality, and Maria Naruse (voiced by Kaori Fukuhara), who has a cute face but always says shocking things. In this way, Basara began to live under the same roof with his two adopted sisters. What’s more terrible is that his father actually left the three of them alone and went on a business trip. What Basara didn't expect was that Mio and Maria's true identities turned out to be Shinko Demon King and Dream Demon, and Basara became their master by accident.
