Seishun Buta Yarou wa Logical Witch no Yume wo Minai

Sakuta has grown accustomed to unusual situations after escaping a time loop with Koga. When he encounters his friend Futaba at a late-night internet café, it should be nothing out of the ordinary—except he is already speaking to another Futaba on the phone. Two versions of Futaba now exist, and neither offers an explanation for this sudden occurrence, referred to as Adolescence Syndrome. One of the Futabas ends up staying at Sakuta’s home, and he must act quickly to resolve the situation before the two doppelgängers come into contact with each other.
