A mysterious girl who has amnesia.
Some people also call her Segami.
The only thing she's able to remember is her name. She possesses an unusual desire to alter history in a way that would settle the disputes between the CPUs and the Sega Hard Girls.
She's a natural leader with lots of charisma, but she occasionally is stubborn about taking orders from others. Her ideas are rather unconventional and sometimes trouble her own teammates.
