Gasaraki - Season 1 Episode 9 The Storehouse

In an attempt to understand the information Miharu has imparted to him, Yushiro returns to his family home to confront his parents. At his ancestral home, Yushiro meets with his instructor, Sorachi, who leads Yushiro into an abandoned storehouse. There Yushiro discovers the cryogenically preserved body of Sorochi's son Ku-ya as well as a body that is probably his, along with the slouched form of a formidably-advanced robot, known as the Kugai. Meanwhile, Yushiro's sister, Misuzu, and Ataka, one of the female TA pilots, have followed Yushiro to the site, where they are surprised by the sudden appearance of Miharu and another of the symbol weapons platforms, known as Ishtars.
