Personality
Kirara is a freshman at Noble Academy who is a 'my pace' sort of girl and is very fashionable. She is active as a model every day, appearing in magazines and fashion shows. Her dream is to be a top model, and she has the strength to pursue it head on.

Becoming Cure Twinkle
Upon learning that Kirara found the third Princess Perfume, Haruka, Minami, Pafu and Aroma find the class she was in to talk to her, but she brushes them off. Later, the group goes to Yumegahama Town, where Kirara was doing a photo shoot, when Close appears with a Zetsuborg. The two Cures defeat it and confront Kirara about the perfume and she returns it to them, thinking it was a gift from a fan. Still determined to find out if she is the third Pretty Cure, they attend a fashion show she is participating in. In her dressing room, Kirara finds a Dress Up Key in her make up case and decides to wear it as a necklace. During the second part of the show, Close appears again and creates a Fashion Model Zetsuborg and it starts to attack, causing everyone except for Kirara and the two Cures to evacuate. The two transform, but are defeated, so Kirara took matter into her own hands to protect her show. Suddenly, her Dress Up Key reacts and Aroma hands her the Princess Perfume and she transforms into Cure Twinkle, quickly dispatching of it with Twinkle Humming. However, even after the other Cures ask her to join the team, she returns the perfume yet again, saying she was too busy to be a Pretty Cure.

Relationships
Haruno Haruka - The two of them are classmates at Noble Academy. During Kirara's fashion show, Haruka goes backstage with some donuts to give Kirara something to eat before the second show began. She even gave her a nickname "HaruHaru" because Haruka's name contains two "Harus".

Kaido Minami - Kirara is the first person to call her "Minami" without adding '-san' or '-sama' like the other students, and they share a friendly relationship.

Cure Twinkle
"The princess of the twinkling stars! Cure Twinkle!" きらめく星のプリンセス！キュアトゥインクル！ ''Kirameku hoshi no purinsesu! Kyua To~uinkuru!'' Cure Twinkle (キュアトゥインクル Kyua To~uinkuru) is the Pretty Cure alter ego of Kirara. She controls the power of stars and transforms with the phrase, "Pretty Cure, Princess Engage!". Her main attack is Twinkle Humming, which she can only perform while in her Mode Elegant.

Attacks

 * Twinkle Humming (トゥインクルハミング To~uinkuru Hamingu) is Cure Twinkle's main attack that can only be used when she is in her Mode Elegant.

Etymology
Amanogawa (天ノ川): Ama (天) means 'sky', which is probably a reference to how stars are in the sky. No (ノ) means 'in' while Gawa (川) means 'river'. So, the full meaning of "Amanogawa" is 'River in the sky' or 'Milky Way', which is a more suitable meaning because of how Kirara is the Princess of Stars.

Kirara (きらら) mean either 'mica' or 'isinglass'. It sounds very similar to "kirakira" which means 'sparkly' or 'glittery'.

Therefore, Amanogawa Kirara means "sparkly river in the sky", "glittery river in the sky", "sparkly Milky Way", or "glittery Milky Way".

Cure Twinkle means the source of light, shines with a flickering light and glimmer.
