Meanwhile, Saito obtains a large pot that was about to be thrown away and converts it into a makeshift hot tub, similar to the hot springs in Japan. While bathing in it at night, Siesta happens to pass by and much to Saito's embarrassment joins him.

At the moment, Albion is in a state of civil war, so Henrietta herself cannot see the prince. Therefore, Louise is sent with a message to Prince Wales requesting that the letter be retrieved. Guiche then enters, revealing that he had "accidentally" heard it all and would be willing to aid the princess. Much to both Louise and Saito's ire, Henrietta accepts Guiche's offer.

With the Prince as the minister, the marriage proceeds and is nearly completed until Saito bursts into the church. Snapping Louise out of her trance, Saito rushes to rescue her.
