Akari is a second year at Takayama Public Middle School who partcipates in no club activities since she thinks they are a waste of time. She loves watching magical girl anime, resulting in how she knew the Shiny Bracelet was a tranformation device to become a superhero. She can be shy to people she doesn't know but can be extremely silly when people get to know her. At school, she is seen reading a lot and when she sets foot in an electronic shop or sees something electronic, she just has to play with it. She tends to solve puzzles in the park from time to time.
When Akari was solving a puzzle at Takayama Park, a Kuroppoi was summoned by Rara and attacked the people at the park. Akari ran to the gates with the crowd of people but had tripped and was trapped in the park with only Rara and the Kuroppoi monster to keep her company. She finds out that Rara want some Legendary Items and was attacked by the Kuroppoi when she tried to get to the park gates while three mascots tried to hurt the Kuroppoi. She was glued to a tree when a red jewel appears in front of her and transforms into a Shiny Bracelet, which freed Akari and gave her the power to transform into Cure Ruby. As Cure Ruby, Akari defeats the Kuroppoi with her attack Fire Explosion and finds out that the three mascots are named Ever, Stone and Glitter and that they came from Twinkle Kingdom.
Hosotera Nanami - She becomes Akari's first friend and gets along a lot better with Akari than Haruka does.
Ever- Ever stays over at Akari house while she is staying at Takayama Town. They get along well and thinks of Akari as a little sister. She likes giving Shigemi fashion tips.
Nagahashi Azami - Akari is always there for Azami when she is upset and hates it when boys dump her since Azami has a lovely personality and doesn't know why boys dump her a week after they started dating. Akari works together with Ever and Shigemi to keep Azami happy.
"The Powerful Flame That Fills the Earth with Fire, Cure Ruby!"
"Hi de chikyū o nuritsubushi kyōryokuna honō wa, Kyua Rubī!"
Cure Ruby (キュア ルビー Kyua Rubī) is Akari's Pretty Cure alter ego. Her theme colour is red and she uses the power of fire to attack Dark Star. When not using her attacks, she is mostly using her hands to throw punches and legs to throw kicks. She can do more powerful punches and kicks if she puts "Fire" before doing her move (e.g Fire Punch).
Akari holds her right arm up with the Sparkle Bracelet on, in front of her and places her red Jewel Shard on her bracelet and yells out "Pretty Cure Glistening Power!" and spins around which starts her transformation. First off, her hair grows longer and goes into a side ponytail and turns red and her eyes go pale red. Her arm warmers then appear followed by her hair accessories and earrings and choker. Her top appears then her bow and the frill. Her skirt than appears and she swipes her hand over her skirt to make her belt appear followed by her boots. She than flys from the sky and does her introduction speech.
Fire Explosion (ファイアー エクスプロージョン Faiā Ekusupurōjon) is Cure Ruby's main purification attack. She gathers all her energy to make a fireball glow in front of her faced up palm and yells the incantation, making the fireball grow larger and fly towards the Kuroppoi, purifying it.
Fire Punch (ファイアー パンチ Faiā Panchi) is Cure Ruby's more powerful punch. She just punches the enemy and yells out the incantation while punching.
Fire Kick (ファイアー キック Faiā Kikku) is Cure Ruby's more powerful kick. She just kicks the enemy and yells out the incantation while kicking.
