Ep. 11: AR Team and Squad Negev battle Sangvis forces led by Alchemist while searching for AR-15.

The AR Team searches for AR-15 with Squad Negev, consisting of Negev, Galil, Micro Uzi, and TAR-21. They are attacked by Sangvis forces led by Alchemist, who attempts to infect them with the Parapluie virus. The group retreats to a planetarium where Galil warns that communications are jammed. M16 leaves to call for reinforcements, while M4 and SOPII follow Galil to rescue her teammates. Griffin reinforcements arrive, allowing the combined forces to defeat the enemy, though Alchemist escapes. Galil enters the planetarium to find her team, but AR-15 suddenly appears before M4 and SOPII. Later, M16 discovers SOPII unconscious and alone, with M4 and AR-15 missing. Gentiane orders all Griffin forces to retreat as a large Sangvis force appears. A flashback reveals AR-15’s resentment toward being created as M4’s obedient friend.
