Can they return to their normal world?!

Peaceful morning.... Tenchi leaves for school while Ayeka and Ryoko see him off. That afternoon, Kiyone drops by the house to report her promotion from Headquarters. Everyone except Mihoshi was happy to hear about her promotion. Then they hear noise from upstairs. On his way home Tenchi hears the noise as well and looks up to find a spaceship in the sky. And his house is not where it's supposed to be. Tenchi meets with Katsuhito, and Ryoohki and Washu, Mihoshi, Kiyone and Nobuyuki come back to the ground in a capsule. According to Washu, the army of Jurai came with their spaceship and took the house with everyone in it. The Jurai army arrested Sasami and Ryoko for treason. Someone who claims to be the legitimate successor of Jurai came into power and ordered the army to arrest Ayeka.
