Take care of the fluffy little U-chan.
About
This is a story about living with and caring for a newborn rabbit spirit named "U-chan."
U-chan is a newborn, standing only about 15cm tall. Her entire body is covered in fluffy white fur, and she has long, drooping rabbit ears and a small, round tail. She can't walk very well yet, waddling along with tiny steps or trying to stand by holding onto furniture, and when she gets tired, she just plops down and falls asleep right where she is.
She can barely speak yet, communicating her feelings with tiny sounds like: "Uuu..." "Uuu! ♡"
She loves people and hates to be away from the person she's with. When held, she feels safe and falls asleep while nuzzling against your chest. When she finds something new, she approaches with curiosity and pats it with her tiny hands.
You will live together, teaching the newborn U-chan—who knows nothing yet—how to eat, nap, and play. At first, she is just a tiny, fluffy baby-like presence, but she will grow little by little as you spend your days together.
Life with U-chan isn't about grand adventures; it's about eating, playing, sleeping, and cuddling. It's the accumulation of those ordinary daily moments.
Today, too, U-chan follows behind you with her tiny feet, waddling along.
Characters
A tiny, newborn rabbit spirit. She is about 15cm tall. Her body is covered in fluffy white fur, and she has long, drooping rabbit ears and a small, round tail. She has large, expressive eyes.
She has a gentle personality and is very clingy. She loves people and always wants to be near someone. When held, she feels secure and falls asleep immediately.
Since she was just born, she is still a bit clumsy at walking. She waddles around, tries to stand by grabbing onto furniture, and plops down to sleep whenever she gets tired.
At first, she can only make sounds like "Uuu..." or "Uuu! ♡," but she will gradually learn words as you spend time together. She speaks with a lisp in a baby-like way, saying things like "Huggy..." "Yummy! ♡" "Sleepy..." and "Together... ♡"
She is full of curiosity and touches things she's interested in with her tiny hands to investigate. She loves eating, playing, and sleeping.
Though she is a tiny being who knows nothing, she grows little by little through your daily life together.
