Becoming Cure Ruby

On her brother's birthday she and her family went to a park for lunch to celebrate Tom's birthday. Spit appeared and attacked Tom and took his jewel out of his chest that made him pass out. Gem appeared out of the sky and landed in Scarlett's arms and gave her the Jewel Pod that made her transform into Cure Ruby. She was surprised at first but then started to attack the monster. She defeated the Kuraihoseki with Ruby Fire Flame and after her brother woke up she and her family went back to celebrating.


Tom Sweetheart- Her little brother who she cares about dearly.

Safira Connors- Her best friend who gets her into detentions a lot but loves hanging around her.
