Watanabe Šion (E07)

As Shion believed he was innocent, Shishigami confesses to her that his body is a robot and has taken many lives in order to feel alive again. He coldly informs her that he will kill everyone in the country. However, Shion begs Shishigami not to leave her behind. Shion cries as she tells Shishigami that the people he's killed had futures and loved ones, and Shishigami makes a proposition. (Crunchyroll)
