Nanamori, Sayoko

七森小夜子

Sayoko Nanamori serves as Itsuki's research assistant. She harbors unrequited feelings for him and reacts with anger if anyone brings up the topic. This dynamic creates a recurring gag in the series: whenever she is especially upset about Itsuki, the windshield wiper on her car performs an intermittent swipe on its own.

Spoiler

In the movie, Nanamori appears only briefly. In the manga, Nanamori is a malevolent Mu agent and facilitates Ayato's escape from TERRA.
