Pretty Baby☆Great Tumult!

Yaya convinces the Guardians to hold a special meeting at her house. It turns out that Yaya just wanted the Guardians to help babysit her baby brother, Tsubasa, because she does not want to. Yaya is jealous of her brother because he is always the center of attention instead of her. When Utau becomes the suspect in the rise of X Eggs, El interrupts the meeting. Amu tries to explain about El and her fourth egg, but Tsubasa begins to cry. Amu is the only one who knows how to take care of a baby. As the group is about to leave, Yaya discovers that Tsubasa is running a fever and become frantic. She rushes him to a doctor who gives Tsubasa some medicine to bring down the fever. Afterwards, the doctor compliments Yaya for being a big sister. Later, Amu finally tells the Guardians about her egg.
