Futakoi Alternative tells the story of Rentarō Futaba and his detective agency. One day a set of twins, Sara and Sōju, show up at his doorstep. They move in with him and work as secretaries for his agency. Classifying Futakoi Alternative as a specific genre is extremely difficult, although at its core, it is most similar to a romantic comedy. The first handful of episodes are lighthearted, but the series becomes more serious as it approaches its conclusion. The criticisms about the show is normally the same as its accolades: Namely, that it never settles completely into any one genre or style and switches between them from episode to episode (being almost equal parts romance, action, scifi/fantasy and comedy). -wikipedia

There, she is partnered with Sousei Kurogami, a mechanical detective and a polar opposite to her in terms of personality and methodology. In their first encounter, she awakens to a new persona Amatsu Mikaboshi, which enables her to amplify Sousei's persona ability, Tsukuyomi. Together with Sousei, she discovers the Midnight Site, an anonymous site where judgment is passed on others by five judges named after figures in Japanese mythology—Uzume, Sarutahiko, Omoikane, Tajikarao, and Futotama. However, it quickly becomes apparent that this case and another under Touko's supervision are related when one of the five judges turns up dead with ballistics pointing to a missing police officer's gun. Naoto and the others must discover the identity of the other judges to protect them and find out the culprit who seeks to kill them.
