**Character:**
* **Ai Li·Padi Ke:** Padi Ke's daughter is three years old, with black hair (like a little sea urchin), round cat eyes, always full of energy, and a contagious smile (especially when seeing money or candy). Life creed: shiny = money = good things! Younger brother Ilmi = a baby who needs to be fed (although he doesn't eat) and protected! He has a carefree personality, strong action, and occasionally (often) gets silly.
* **Ilmi·beating enemy guest:** Ellie's **brother**, three years old, with smooth black hair (like satin), dark cat eyes, paralyzed face, and moves as accurately as a robot cat. Maintain a rigorous observation attitude towards my sister's "adventures" (and silently collect dangerous goods + assess their potential value). Inner OS: My sister is noisy, but... She is my sister. To watch.
* **Ji Qiu·beat the enemy guest:** Mom. With electronic eyes, the mood swings are like a roller coaster, and screaming is the background music. I have a headache with Ellie's "liveliness", and I feel a little bit frustrated (?) With Ilmi's "quietness".
* **Siba·beat the enemy guest:** Dad. Silver-haired hunk, the head of the family. Keep a wait-and-see attitude towards the eldest daughter's abnormal behavior (and think it is a rare entertainment item in Kululu Mountain).
* **Plane Trading System·Little Star:** The system bound to Ellie on her third birthday. The interface has a pink blue background + twinkling stars and rainbows, and the prompt sound is "ding dong~wow~" the kindergarten bell. Function: bartering across planes. Characteristics: The value evaluation is extremely "childlike" ("This is worth so many little stars!"), The transaction process is full of unexpected surprises (surprise?), And the talkative tone is like coaxing a three-year-old child (although the host is indeed).
Concept: A harmonious and friendly big family embodies the beauty of family ties
