Siren - In the past Hummy was Siren's friend who acted as her sister figure and taught her how to sing. Although Siren betrayed Major Land by joining Mephisto, Hummy still considers her a friend, much to the annoyance of Siren, but this is later shown to appeal to Siren's heart when she is brainwashed.
Candy - In the Pretty Cure All Stars New Stage Movie, Hummy appears to have a good relationship with Candy, the mascot of the Smile Pretty Cure, as seen when she offers Candy one of Kanade's cupcakes and even tells Hibiki and Miyuki that they are friends.
Before Hummy was chosen to sing the Melody of Happiness, Hummy and Siren were friends. Some time before the ceremony for the Melody of Happiness, she was chosen to be the Fairy of Songs, but was never told of her responsibilities, and did not see Siren before it started.SPC01 Later it is revealed how Siren helped Hummy when someone played a cruel trick by giving Hummy the wrong score for the contest to see who would sing the Melody of Happiness and how a lie concerning this led to Siren's defection to minor land.
The Melody of Happiness
When the ceremony starts, Hummy is to sing the Melody of Happiness to the citizens of Major Land and their empress, Aphrodite. As Hummy is about to sing, the ruler of Minor Land, Mephisto, appears, stealing the Legendary Score and changing the melody to the Melody of Sadness. Siren, who has joined Minor Land and was the previous Fairy of Songs, starts to sing the new score, making the audience very sad. Aphrodite proceeds to scatter the score into several notes and sends them to Earth, ordering Hummy to take with her the Fairy Notes to find the scattered notes. At the same time, Mephisto sends Siren and the Trio the Minor to do the same. Unknown by Hummy, however, she was sent also to find the legendary warriors, Pretty Cure, whom shall protect the Melody of Happiness.
As she gets to the human world, she witnesses Siren and the Trio the Minor cornering a defenseless girl. She of course tries to stop Siren. The girls is revealed to be Hojo Hibiki, and her friend Minamino Kanade. Both of them have a G Clef in their bodies. Siren and Bassdrum try to take them from the girls, but they had a shining light defending them. Hummy then realizes that they are Pretty Cure and has two Fairy Tones help them transform.SPC01 Much to their dismay, the girls are not presently friends, and their fighting makes them return to their original forms very fast. After the villains and their Negatone leave, Hummy tries to help them become friends again, but can only watch as Kanade leaves them. She tries to have Hibiki explain the circumstances, and is told that the girls had a fallout when Kanade left Hibiki for some other girls at the beginning of the school year. However, in the end, Hummy manages to get them to work together and to come to an agreement. They then transform once more to recover their record that was stolen from them.SPC02 As they continue to collect notes from everyone, the Melody of Happiness is completed and ready to go. As Hummy sings the melody, everything turns back to normal.SPC48
