|“||I'll do my best!||„|
|~ Setsuna Higashi|
When She was Eas, she had silver hair with a black hairband. A Black and Scarlet jacket buttoned by 2 red daimonds. he wore long black gloves with bracelets attached to it. Black Leggings with bows and were high heels. As Setsuna, she has dark purple hair and in her casual clothes, she wears a red-pink shirt and a white vest. She wears a beige skirt and black boots. As Cure Passion, she has pink hair with a hair band in the middle, a red daimond and 2 hearts on the side with wings. She wears a Red long dress and black leggings with heels with white and black ribbons around, including bows.
Setsuna starts out as a cold and isolated girl, loyal only to Moebius and act sly. When she, as Setsuna, meets Love, Love's nature and the "happiness" Love shows her makes her slightly open up to the girls. She begins to open her heart, cracking piece by piece to them, but too stubborn to realize it. She have a stubborn mind, however, as she refuses to accept the fact that she has weaknesses. This is shown every time Soular or Westar asks her about Pretty Cure after losing to them, in which she throws small fits and leaves, usually thinking that she will be the one defeating Pretty Cure.
After switching sides, she seems to have lost most of her stubborn mind, and is typically sweet and reserved and patient, though her nature may be due to naivety and guilt when she remembers her sins of doing evil things hurting her friends in the past but over it when she faced "herself". She became kind hearted and loves her friends and Setsuna and Love were like sisters.
Happiness Hurricane - Cure Passion summons her Passion Harp and recites the first half of the incantation. She lights up the strings on the harp, then gives the harp a downward stroke. The double heart-shaped adornment lights up, and she summons a flurry of feathers as she recites the second half of the incantation. Declaring the attack, she begins spinning as a storm of hearts and angel feathers surround the opponent. Passion stops spinning and thrusts the harp upward, then centers it. As she spins the harp around, the enemy becomes purified in a red heart-shaped bubble with hearts surrounding the bubble.
