The Four Assassins
Kaaya and Neeba make their way across a vast expanse of water, unaware that four assassins are watching them, and realize the area's instability reflects Gilgamesh's own heart. The duo are eventually attacked by two of the assassins, which happen to be the soul-less artificial soldiers released from Pazuz's coffins, but manage to escape to the next floor through a whirlpool. Both Jil and Gremica's parties make their way through a jungle environment and everyone is separated when two assassins suddenly attack. When Gremica's assistant Acra takes out the young girl assassin, Gremica's party is able to flee while Jil and his party is left to finish off the other before they move on to the next area. In the jungle, Coopa, Melt, and the Golden Knights find the unconscious girl assassin. In Meskia, Kelb and Ethana separately witness Gilgamesh's increasingly cruel behavior as he plans to invade neighbouring countries.
