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.

After telling Haruto that he didn't have the right to protect Asahi, Takanori used his Divine Sense to teleport Haruto and himself to the Monochrome world. Takanori and Haruto butt heads, but Satsuki manages to intervene before it gets too far. They search for one of the former Subaru members Clive, when Takanori reappears to try to take Asahi away with the help of two major elite guilds.

The elite guilds Southern Cross and the Brill Society capture Asahi after Takanori falls for their ruse. In order to save Asahi, Haruto goes up against thousands of enemies alone, but ends up outnumbered until Satsuki and Takanori come to his aid. The three of them finally reach Asahi, only to discover that Angelus has taken control of her spirit in order to control the Prophet Art.
