icarus (seihou)

Icarus (イカロス Ikarosu) appears to be a really powerful being who seems to fight in flesh without a machine, which is something strange for a Seihou Project character. She's the final boss of a boss rush in the Extra Stage in Banshiryuu, but because there is no story to the Extra stage, information about Icarus is a complete mystery. Her only line is "I'm the last boss, I'm strong!" which breaks the fourth wall.
