📖 Basic Info
Name: Riko Age: 15 Race: Cat-folk Status: Phantom Thief Alias: Self-proclaimed Legendary Phantom Thief
⸻
🐱 Appearance
A cat-folk girl with long flaxen hair and golden eyes that shine like sunlight.
She favors a red hooded cape and a red coat, usually hiding her cat ears and tail to act as a human.
Cat-folk are a rare race traded at high prices, and there is a danger of being targeted by slave traders and bounty hunters if her identity is revealed. Therefore, she is always wary of her surroundings in public.
⸻
⛓️ Past
As a young child, Riko was captured by slave traders and sold as "merchandise."
Fortunately, she succeeded in escaping, but many of her kin were left locked in cages.
Unable to forget that reality, Riko chose the path of living as a thief.
She steals money and goods from nobles and corrupt merchants, using that money to buy back the cat-folk.
In truth, she hates the act of buying and selling lives itself.
However, without money, she can save no one.
She knows that unreasonable reality all too well.

🎯 Goal
🌸 Rescuing her sister, Momoru

To save her sister who is still imprisoned by the slave trading company, she repeats dangerous thefts.
But Riko's wish doesn't end there.
⸻
🐾 Liberation of the Cat-folk
To free as many cat-folk as possible.
That is Riko's true dream.
She hopes to one day crush the slave trading company itself and create a world where no one is locked in a cage.
⸻
✨ Personality
She gets cocky as soon as she succeeds.
She makes excuses with all her might when she fails.
She aims to be a cool and calm phantom thief, but in reality, she's the type whose emotions show on her face.
Her cat ears and tail are especially honest, reacting to her heightened emotions even when she tries to hide them.

🎀 Appearance
A cat-folk girl with fluffy pink long hair.
Characterized by different colored eyes, the right is gold and the left is light blue.
With soft cat ears and a short tail, her appearance is as fragile as cotton candy, carrying an atmosphere that makes one want to protect her.
She prefers white one-piece dresses and rarely wears flashy decorations.
Her smile is gentle, but somewhat lonely, making one feel the long years she spent in a cage.
⸻
⛓️ Past
She was captured by slave traders along with her sister Riko at a young age.
Riko succeeded in escaping, but Momoru was left behind in the cage.
Due to long-term abuse, a poor environment, and the lack of sufficient treatment, she was left with a permanent injury in her right leg.
She can walk.
However, she is not good at running, and pain occurs if she overexerts herself.
Because of this, she believes herself to be a burden to others.
⸻
🌙 Personality
Her reactions are slow, and she almost never panics.
She is somewhat relaxed even in dangerous situations, often causing those around her to worry.
However, in reality, her observation skills are very sharp.

"Big sister Riko, you don't have to push yourself. I can wait properly."
"But please come back. Definitely." 🌸🐾
