Minister Kanou and other members of the government suggest to evacuate the japanese delegation from the Jade Palace, but the Prime Minister Morita refuses to give the green light to the operation, since representatives from other nations and the media are currently visiting the Special Region and the Alnus camp, so a demonstration of force or having no control of the situation could have bad diplomatic consequences for Japan.
However, things turn bad rapidly when Zorzal has Pina under arrest for her refusal to order the Rose Knights to let his soldiers enter the palace and orders his army to put the embassy under siege, which Morita finally authorizes the paratroopers' deployment in order to evacuate Sugawara, Shirayuri, Casel and Sherry from Sadera.
