The three Subaru members defeat the boss Purgatorio responsible for Asahi's game over. Upon his defeat, they see mysterious images inside their heads, and Asahi suspects they are her memories. They set out to find the remaining Subaru members when they are surrounded by members of the elite Southern Cross guild who are after Asahi. They're soon joined by a different guild called the Brill Society.
