Suite Precure♪Episode 1 English FanDub

Kanade excels at studies but isn't good at sports. She is popular at school and dreams of being a pâtissière when she grows up and taking over her parents' cupcake shop, the Lucky Spoon. She also has a strong love for cats and an affinity for their paws.

Before her brainwashing, Siren was shown to be a very kind and caring cat who took care of Hummy and enjoyed her company. But when she began to get envious of others' achievements, she found herself growing cold towards Hummy and she took Mephisto up on his offer. In this time she became cold, calculative, and kept to herself. She lacks sympathy and is unwilling to talk about her pain. 

Bassdrum has a big ego and wants to be the leader of the group so he clashes with Baritone and Siren, who have ambitions of their own. While he comes up with several schemes to beat the Cures, his haughtiness almost always causes him to overlook several details and his efforts end in no avail.

While ruling Minor Land, Mephisto was mostly seen as comic relief and barely fearsome, with his personality resembling a schoolyard bully rather than an evil villain.

Hummy can be naive, and somewhat of an airhead. She is rarely ever sad or unhappy, and is not even shocked when she meets Siren as an enemy. She is also very positive and can get rid of a bad thought in minutes.

Aphrodite (アフロディテ, Afurodite)? is the Queen of the nation "Major Land" in Suite Pretty Cure♪. She hosts the anniversary of the "Melody of Happiness" to pray for the peace of all worlds. When Mephisto shows up to ruin the concert she scatters the notes to the winds and sends Hummy to Earth with the Fairy Tones to find Pretty Cure and gather them all up again. In episode 36 it is revealed that she is Ako's mother and the wife of Mephisto.

Seika is passionate about baking and very wise with an elegant way of carrying herself and gentle disposition. She listens to Kanade and offers her advice when she's troubled.

The Fairy Tones (フェアリートーン, Fearī Tōn)? are jewel-like mascots that provide aid to the Suite♪ Cures. They grant power and abilities when they are inserted into the Cure Modules, Miracle Belltier, Fantastic Belltier, or Love Guitar Rod.

Hibiki is a bright, albeit somewhat klutzy girl who carries a strong sense of justice. She's very bold and outgoing, though she has a tendency for hot-bloodedness that often manifests as a dislike of losing. She has a distaste for underhanded tactics, believing hard work and effort must be put into things to get them right. Though usually happy-go-lucky and energetic, when angered or faced with a tough situation, Hibiki has a tendency to become more subdued and serious.
