Prologue

Ua-3846 is the daughter of Ae3803 and U-1146. She was born and made to be a Red Blood Cell. However, she feels like she was made for the wrong job. One day, her father has to go fight an army of Cancer Cells that could kill the human body. Afraid that he will be killed, she takes his place while her parents were sleeping and dresses up as a White Blood Cell. Will she be worthy and strong enough to destroy Cancer?

If this plot seems familiar it's because it's heavily inspired by Mulan. Also credits to @screams-in-distress for the awesome fanart!
