Yu Yuyu has a huge world, and in that world she has a huge dream.
All alone in that dream, she picks up trash, hoping to reclaim her grand dream.
She picks up a little here and a little there, and finally finds a kitten.
Now she's no longer homeless. She has her first identity: a kitten.
One day, a girl brings her another gift: a beautiful sun.
After that, lots of people hear her story, and they all want to make her huge dream come true, so they come over one after another to bring her gifts.
But she feels a little worried, looking at the much larger humans from inside the kitten's body.
Don't come too close. I really like you all, but I don't want you to disappear either.
This is really just a secret identity story. Everyone is imagining all kinds of love and hatred between her various secret identities.
In reality, she's just trying to contribute and keep the people who accidentally, or perhaps deliberately, entered this dream from dying.
She never imagined that these secret identities would become the one person each of them could never forget.
