S1·E8 Inferno

Amid evidence that the Japanese government is involved in some sort of cover-up regarding the TAs, Yushiro's elder brother Kazukiyo Gowa meets with Hiraku Nishida, an elderly, blind warrior who wishes to unleash selective violence against the Japanese people in order to strengthen Japan against growing opportunism and selfishness. At the Gowa laboratory the plot takes a startling twist when Miharu breaks into the Gowa headquarters to retrieve the missing components taken by the Japanese TAs in Belgistan. As she exits the plant, Miharu reveals to Yushiro the startling secret she has uncovered during the raid - the Gowa family refers to Yushiro as ""the test subject"" and that the real Yushiro Gowa has been deceased for years. As the episode ends, Yushiro's entire existence is mired in uncertainty.
