Android 9 is a robot created by Dr. Mechatun. Android 9, or Nina, wasn't originally an android. She was once just a 16 year old cat girl that lived at Lavender Island. She was in an car accident that left her with sever injuries, and a broken skull. She was thought to be dead, but Dr. Mechatun had created an android replica of her and put her brain into the replica to give it life.

At first, Nina seem emotionless, but when you get to know her, she's as cheerful and playful as can be.
