Not long after Chibi-usa returns to the future Usagi and Luna are walking through the park.

Meanwhile a small (as in three foot tall) girl with red hair in heart shaped odango floats to the ground with an open umbrella (Mary Poppins junior J ). She lands on the ground and a sudden gust of wind blows the umbrella from the girls grasp. The umbrella floats on the wind and (in slow motion) Usagi catches it. She gives the umbrella to the little girl who accepts it and smiles in true anime line eye, big smile style and Usagi looks a little surprised at the girl, seeinf the smile she smiles and pats the girl on the head. "Kawaii," she says before walking away, Luna at her heels.

Later, when they are walking down a narrow street Luna stops Usagi, because the little girl is following them. Usagi runs up to to her and squats down to her level. "Whats your name?" she asks.

The little girl considers then for a mment and then does that dumb/cute smile again and says "Chibi!"

"Wheres your mother?"

"Chibi!"

Usagi smiles then sweatdrops. She covers her mouth with one hand to hold a very obvious conversation with Luna. Then Luna looks up and is startled - the girl has vanished!

Later Usagi gets home and is scolded by her mum for leaving her younger sister alone in the park to walk home. Usagis "little sister" appears at the doorway, her name is (surprise surprise) Chibi Chibi!
