The pursuit lands them in the outdoor areas of World's World. Calbee tries to charm Yuri while looking for opportunities to make his escape.

On the last day before the spaceport reopens, a bomb destroys Touma and the girls' residence. Kei and Yuri assume their bodyguard positions again. Touma attempts to isolate the location of the perpetrator, but everywhere they go, more androids continue to threaten Touma's life.
