Ladyblur

Lizzie Robin (AKA Ladyblur) moved to Japan where her older brother resided so she could explore and sight see with her dear sibling. One day Lizzie's brother was killed, his soul and his own self sucked away, his body stolen, and Neon Saver had been the one to blame. Lizzie was devastated after seeing her sibling's passing, and mourned her loss. Neon Saver headed for Lizzie. She had been too weak. Damaged to the head badly, she died, but a fortunate moment had arrived as Strike Man / Jan Juden saved Lizzie with a blur spyragem from Neon Saver dropping her from a 5 scale parking building. Jan (AKA Strike Man) told Lizzie where he lived as she needed to find a way to thank him for saving him. Jan gave Lizzie the Butterfly Key to turn into Ladyblur, and fight a new nemesis, Heartbreak,  who was being a creep to her.
