Sawatari Shochou

The head of the research institute where Yoshino and Ubukata work, he is troubled by Yoshino's self-centered actions. As a result, he temporarily banned Yoshino from entering the institute as a disciplinary measure. However, when Yoshino entered the institute with Asahi during the suspension, he declared a dismissal notice.

He is not very competent, ignoring messages from Aoi and shouting at those around him. Ultimately, he disposed of Aoi along with the satellite, attempting to cover up the evidence that their research was the cause of the disruption to the lifeline. Although the disposal of the satellite was successful, his whereabouts after that remain unknown.
