The Imperial Army attempts to break through the embassy are repelled by the Rose Knights, but with the massive difference in numbers it's just a matter of time until the Jade Palace's fall, so Bozes starts plans to escape to Italica in order to form a new government to oppose Zorzal.
Meanwhile, in Rondel, Shandy discovers that Norra (The Pied Piper) is planning another assassination attempt against Lelei, so Itami and the others prepare themselves to stop him. As expected, during Lelei's presentation, two more assassins try to kill her, but they're both thwarted by Itami and the others: however, at the final moment, Shandy tries to stab Lelei, but is saved thanks to the armor under her dress. Interrogated about her betrayal, Shandy reveals that the Pied Piper forced her to kill Lelei in order to save Pina, who has been formally accused of high treason and jailed.
So, Itami and the others decide to turn back to the Imperial Capital while at the same moment the JSDF, having received the complete green light from Tokyo, prepare themselves to launch a massive operation against the capital to break the Jade Palace's siege.
