Publishing company Kadokawa announced an original video anime adaptation of Pochi Iida's Ane Naru Mono (The Elder Sister-like One) manga on Monday.
Since the death of his parents, young Yuu has suffered considerably from neglect and abuse at the hands of his adoptive relatives, who leave him to his own resources to survive. Fortunately, a girl named Chiyo comes to his aid and offers to take care of Yuu while acting as his older sister. However, Chiyo is not what she seems, and Yuu knows all too well that her intentions are far from innocent. In exchange for her generosity, Yuu must supply Chiyo with his "life potential."

Based on her doujinshi of the same name, Iida began serializing the supernatural romance manga in Dengeki G's Comic magazine in March 2016. Kadokawa will publish the fourth volume on January 10. Ane Naru Mono has a cumulative 750,000 copies of its volumes in print.
Kadokawa released a television commercial last July, featuring voice actress Yui Horie (Bakemonogatari, Black Bullet) as the main female character Chiyo.
