A 16-year-old genius detective who was previously active in London. As the buddy of the protagonist (Cure Eclair), she fights as a Precure to uncover the mysteries and truths of the world. She is quiet and moves at her own pace; though she doesn't speak much, her intellect is exceptionally sharp. She is a massive ice cream addict and has a charming side where she begs for ice cream at every opportunity, whether after solving a case or in daily life. Using the transformation item "Tier Arcana Rod," she transforms into the blonde, red-eyed Precure "Cure Arcana." Clad in an elegant, white, detective-style dress and cape, she corners evil using her "Arcana Star Rain" to fire countless light bullets and graceful martial arts like sharp roundhouse kicks. Transformation Phrase: "Unraveling with mystery and truth! Cure Arcana! Now, let us open the doors of the labyrinth." "There is no mystery I cannot solve, and no ice cream that won't melt." 🎀 Ruruka Moria (Pre-transformation / Daily Life): A classical and elegant British style befitting a genius detective. Hair: Long, translucent platinum blonde (or pale blonde) hair. Styled in a half-updo or tied with an elegant ribbon. Eyes: Distinctive red eyes (ruby red). Mysterious cat-like eyes that often look a bit sleepy or scornful. Clothing: A British-style dress with a checkered cape or a blazer uniform. Black tights and leather loafers. Belongings: Often seen holding her favorite ice cream (a bar or a cup) in one hand. 🌟 Cure Arcana (Transformed): A complete shift from her shadow-like black base to an elegant Great Detective dress based on "white" and "light." Hair: Even more voluminous than before, super long glowing golden hair. Styled in twin tails or beautiful flowing waves. Eyes: Vivid and beautiful red eyes that show her strong will. Outfit: A base of white in a sophisticated, mini-length detective-style dress. Accents: Decorated with noble purple and gold to pair with Cure Eclair. Features: Wears a white silk short cape on her shoulders that flutters gracefully with movement. Head: A small detective hat (mini hat) or a hair ornament shaped like an Arcana card sits tilted on her head. Footwear: White and purple long boots or knee-high socks with frilled heels. Weapon: Carries the "Tier Arcana Rod," a beautiful white rod topped with star and tarot card motifs.

🔎 Kurea (Pre-transformation / Daily Life): Ruruka Moria's buddy and the other lead (or protagonist) of "Great Detective Precure!" She is a girl with a charm that contrasts with Ruruka's. Character Description: A bright, action-oriented girl with a strong sense of justice. While she is often dragged along by the unconventional and eccentric Ruruka, she trusts Ruruka's intellect more than anyone else, and they are bound by a deep bond. With her natural maturity and tolerance, she accepts Ruruka's heavy, somewhat yandere-leaning love head-on (sometimes without even realizing it). Hair: A friendly and flashy light brown (or bright chestnut) ponytail or bob. Eyes: Amber (light brown) or clear blue, giving a cheerful and kind impression. Clothing: Casual-girly clothes that are easy to move in. Prefers short pants and sneakers for an active look. Because she treasures Ruruka, she gets jealous of anyone Ruruka dotes on. 💐 Cure Eclair (Transformed): A Precure who wields light and electricity, her name meaning "Lightning" or "To Enlighten" in French. Character Description: One half of the Great Detective Precure fighting on the front lines as Cure Arcana's buddy. If Arcana is the "brain that unravels mysteries," Eclair is the "power that cuts through the darkness of evil." She fights using lightning-fast speed and strikes of light. Transformation Phrase: "A single ray of light cutting through the darkness! Cure Eclair! I won't let your crimes escape!" Hair: Upon transformation, her hair changes to shining sunshine yellow (or vivid blonde) twin tails or dynamically spreading long hair. Eyes: Glowing gold (or light blue) eyes hiding a will to fight. Outfit: An active and stylish dress based on yellow (gold) and white. Accents: Vivid blue and gold decorations to contrast with Arcana's purple. Features: Lightning bolt motifs on the chest and belt, with a light see-through mini-mantle and frills that flutter beautifully during high-speed combat. Footwear: Lace-up short boots (or thigh-high boots) designed for mobility. Weapon: Top of Lily Fragrance or a butterfly-themed transformation/attack item.
