“Tabitha’s Secret”
“Tabasa no Himitsu” (タバサの秘密)

It’s summer vacation, and many students are traveling back to their families. Kirche goes along with Tabitha to her home. As a result, Louise and Saito are alone for once; however, mischief is still plentiful. Kirche learns that Tabitha’s real name is Charlotte, that she is the Princess of Gallia, and that she has a rather tragic past. Her reason for returning home is revealed to be a mission from her uncle, the King of Gallia. Meanwhile, Montmorency is upset that Guiche has been flirting with other girls, and makes a love potion to try to slip into Guiche’s drink. Saito obtains a large pot that was about to be thrown away and, at night, fashions it into a hot tub, similar to those in Japan. While Saito relaxes in the tub, Siesta passes by and joins him, much to his embarrassment. Louise sees the two together and becomes so frustrated that she interrupts Guiche and Montmorency, and chugs the drink with the love potion in it. When Saito returns to her room, Louise gets flustered and falls completely in love with him.
